HttpCache

Cache Control.

Description:: Configuration is not thread safe and must occur at initialization time when the application is single threaded. If the configuration is modified when the application is multithreaded, all requests must be first be quiesced.

See Also:: httpAddCache, httpUpdateCache

API Stability:: Internal.

Fields:

MprTicks	clientLifespan	Lifespan for client cached content.
MprHash *	extensions	Extensions to cache.
int	flags	Cache control flags.
MprHash *	methods	Methods to cache.
MprTicks	serverLifespan	Lifespan for server cached content.
MprHash *	types	MimeTypes to cache.
MprHash *	uris	URIs to cache.

void httpAddCache (struct HttpRoute *route, cchar *methods, cchar *uris, cchar *extensions, cchar *types, MprTicks clientLifespan, MprTicks serverLifespan, int flags)

Add caching for response content.

Description:: This call configures caching for request responses. Caching may be used for any HTTP method, though typically it is most useful for state-less GET requests. Output data may be uniquely cached for requests with different request parameters (query, post, and route parameters).

When server-side caching is requested and manual-mode is not enabled, the request response will be automatically cached. Subsequent client requests will revalidate the cached content with the server. If the server-side cached content has not expired, a HTTP Not-Modified (304) response will be sent and the client will use its client-side cached content. This results in a very fast transaction with the client as no response data is sent. Server-side caching will cache both the response headers and content.

If manual server-side caching is requested, the response will be automatically cached, but subsequent requests will require the handler to explicitly send cached content by calling httpWriteCached.

If client-side caching is requested, a 'Cache-Control' Http header will be sent to the client with the caching 'max-age' set to the lifespan argument value (converted to seconds). This causes the client to serve client-cached content and to not contact the server at all until the max-age expires. Alternatively, you can use httpSetHeader to explicitly set a 'Cache-Control' header. For your reference, here are some keywords that can be used in the Cache-Control Http header.

'max-age' Maximum time in seconds the resource is considered fresh. 's-maxage' Maximum time in seconds the resource is considered fresh from a shared cache. 'public' marks authenticated responses as cacheable. 'private' shared caches may not store the response. 'no-cache' cache must re-submit request for validation before using cached copy. 'no-store' response may not be stored in a cache. 'must-revalidate' forces clients to revalidate the request with the server. 'proxy-revalidate' similar to must-revalidate except only for proxy caches.

Use client-side caching for static content that will rarely change or for content for which using 'reload' in the browser is an adequate solution to force a refresh. Use manual server-side caching for situations where you need to explicitly control when and how cached data is returned to the client. For most other situations, use server-side caching.

Parameters:

route	HttpRoute object.
methods	List of methods for which caching should be enabled. Set to a comma or space separated list of method names. Method names can be any case. Set to null or '*' for all methods. Example: 'GET, POST'.
uris	Set of URIs to cache. If the URI is set to '*' all URIs for that action are uniquely cached. If the request has POST data, the URI may include such post data in a sorted query format. E.g. {uri: /buy?item=scarf&quantity=1}.
extensions	List of document extensions for which caching should be enabled. Set to a comma or space separated list of extensions. Extensions should not have a period prefix. Set to null, '' or '*' for all extensions. Example: 'html, css, js'. The URI may include request parameters in sorted www-urlencoded format. For example: /example.esp?hobby=sailing&name=john.
types	List of document mime types for which caching should be enabled. Set to a comma or space separated list of types. The mime types are those that correspond to the document extension and NOT the content type defined by the handler serving the document. Set to null or '*' for all types. Example: image/gif, application/x-php.
clientLifespan	Lifespan of client cache items in milliseconds. If not set to positive integer, the lifespan will default to the route lifespan.
serverLifespan	Lifespan of server cache items in milliseconds. If not set to positive integer, the lifespan will default to the route lifespan.
flags	Cache control flags. Select HTTP_CACHE_MANUAL to enable manual mode. In manual mode, cached content will not be automatically sent. Use httpWriteCached in the request handler to write previously cached content. Select HTTP_CACHE_CLIENT to enable client-side caching. In this mode a 'Cache-Control' Http header will be sent to the client with the caching 'max-age'. WARNING: the client will not send any request for this URI until the max-age timeout has expired. Select HTTP_CACHE_RESET to first reset existing caching configuration for this route. Select HTTP_CACHE_SERVER to define the server-side caching mode. Select HTTP_CACHE_UNIQUE to uniquely cache requests with different request parameters.

HttpQueue

Queue object.

Description:: The request pipeline consists of a full-duplex pipeline of stages. Each stage has two queues, one for outgoing data and one for incoming. A HttpQueue object manages the data flow for a request stage and has the ability to queue and process data, manage flow control, and schedule packets for service.

Queue's provide open, close, put, and service methods. These methods manage and respond to incoming packets. A queue can respond immediately to an incoming packet by processing or dispatching a packet in its put() method. Alternatively, the queue can defer processing by queueing the packet on it's service queue and then waiting for it's service() method to be invoked.

If a queue does not define a put() method, the default put() method will be used which queues data onto the service queue. The default incoming put() method joins incoming packets into a single packet on the service queue.

Data flows downstream from one queue to the next queue linked via the nextQ field.

Description:: This initiates writing buffered data (flushes) by scheduling the queue and servicing the queues.

If blocking mode is selected, all queues will be immediately serviced and the call may block while output drains. If non-blocking, the queues will be serviced but the call will not block nor yield. In blocking mode, this routine may invoke mprYield before it blocks to consent for the garbage collector to trun. Callers must ensure they have retained all required temporary memory before invoking this routine.

This routine when used with HTTP_BLOCK should never be used in filters, connectors or by handlers outside their open, close, ready, start and writable callbacks.

ssize httpWrite (HttpQueue *q, cchar *fmt, ...)

Write a formatted string.

Description:: Write a formatted string of data into packets onto the end of the queue. Data packets will be created as required to store the write data. This call always accepts all the data and will buffer as required. This call may block waiting for the downstream queue to drain if it is or becomes full. Data written after httpFinalizeOutput or httpError is called will be ignored.

Handlers may only call httpWrite in their open, close, ready, start and writable callbacks as these are the only callbacks permitted to block. If a handler needs to write in other callbacks, it should use httpWriteBlock and use the HTTP_NON_BLOCK or HTTP_BUFFER flags.

Filters and connectors must never call httpWrite as it may block.

Parameters:

q	Queue reference.
fmt	Printf style formatted string.
...	Arguments for fmt.

Returns:: A count of the bytes actually written.

ssize httpWriteBlock (HttpQueue *q, cchar *buf, ssize size, int flags)

Write a block of data to the queue.

Description:: Write a block of data onto the end of the queue. This will queue the data and may initiaite writing to the connection if the queue is full. Data will be appended to last packet in the queue if there is room. Otherwise, data packets will be created as required to store the write data.

This call operates in buffering mode by default unless either the HTTP_BLOCK OR HTTP_NON_BLOCK flag is specified. When blocking, the call will either accept and write all the data or it will fail, it will never return "short" with a partial write.

In blocking mode (HTTP_BLOCK), it blocks for up to the inactivity timeout specified in the stream->limits->inactivityTimeout value. In blocking mode, this routine may invoke mprYield before blocking to consent for the garbage collector to run. Callers must ensure they have retained all required temporary memory before invoking this routine.

In non-blocking mode (HTTP_NON_BLOCK), the call may return having written fewer bytes than requested.

In buffering mode (HTTP_BUFFER), the data is always absorbed without blocking and queue size limits are ignored. In buffering mode, this routine may invoke mprYield if required to consent for the garbage collector to run. Callers must ensure they have retained all required temporary memory before invoking this routine.

Data written after calling httpFinalize, httpFinalizeOutput or httpError will be discarded.

Parameters:

q	Queue reference.
buf	Buffer containing the write data.
size	of the data in buf.
flags	Set to HTTP_BLOCK for blocking operation or HTTP_NON_BLOCK for non-blocking. Set to HTTP_BUFFER to buffer the data if required and never block. Set to zero will default to HTTP_BUFFER. This call may yield via mprYield if flags are set to HTTP_BLOCK.

Returns:: The size value if successful or a negative MPR error code.

ssize httpWriteString (HttpQueue *q, cchar *s)

Write a string of data to the queue.

Description:: Write a string of data into packets onto the end of the queue. Data packets will be created as required to store the write data. This call may block waiting for the downstream queue to drain if it is or becomes full. Data written after httpFinalizeOutput or httpError is called will be ignored.

Parameters:

q	Queue reference.
s	String containing the data to write.

Returns:: A count of the bytes actually written.

The form of the "directory" rule is: "directory pathString". For example: "directory /stuff/${request:pathInfo}.txt" The "exists" rule tests if the condition argument is present in the file system. The form of the "exists" rule is: "exists pathString". For example: "exists ${request.filename}.gz", The match directory tests a regular expression pattern against the rest of the condition arguments. The form of the match rule is: "match RegExp string". For example: "match https ${request.scheme}".
details	Condition parameters. See httpSetRouteTarget for a list of the token values that can be included in the condition rule details.
flags	Set to HTTP_ROUTE_NOT to negate the condition test.

Returns:: "Zero" if successful, otherwise a negative MPR error code.

If route maps have been defined, the filename may be mapped to a preferred compressed or minified filename to serve.

After computing the filename, this routine calls httpSetFilename to set the HttpTx.filename, ext, etag and fileInfo fields. If a filename has already been defined by a prior call to httpMapFile or httpSetFilename, this routine will do nothing. To reset a prior filename, use httpSetFilename with a null argument.

Parameters:

stream

HttpStream stream object.

To use the traditional (uncommon) repeat syntax, back quote with "\\". Sub-expressions and token expressions are also available in various rules as numbered tokens "$1". For example: the pattern "/app/(.*)(.html)$" will permit a file target "$1.${request.Language=fr}.$2".

Parameters:

route	Route to modify.
pattern	Route regular expression pattern.
flags	Set to HTTP_ROUTE_NOT to negate the pattern match result.

int httpSetRouteTarget (HttpRoute *route, cchar *name, cchar *details)

Set a route target.

Description:

This configures the route pipeline by defining a route target. The route target is interpreted by the selected route handler to process the request. Route targets can contain symbolic tokens that are expanded at run-time with their corresponding values. There are three classes of tokens:

System and Route varibles - such as DOCUMENTS_DIR, HOME_DIR, BIN_DIR, PRODUCT, OS, VERSION.
Route URI tokens - these are the braced tokens in the route pattern.
Request fields - these are request state and property values.

System and URI tokens are of the form: "${token}" where "token" is the name of the variable or URI token. Request fields are of the form: "${family:name=defaultValue}" where the family defines a set of values. If the named field is not present, an optional default value "=defaultValue" will be used instead. These supported request field families are:

header - for request HTTP header values
param - for request params
query - for request query field values
request - for request details
Any URI pattern token

For example: "run ${header:User-Agent}" to select the client's browser string passed in the HTTP headers. For example: "run ${field:name}" to select the client's browser string passed in the HTTP headers. For example: "run ${name}.html" where {name} was a token in the route pattern. For example: "run ${name}.html" where {name} was a token in the route pattern. The supported request key names are:

clientAddress - The client IP address
clientPort - The client port number
error - Any request or connection error message
ext - The request extension
extraPath - The request extra path after the script extension
filename - The mapped request filename in physical storage
language - The selected language for the request
languageDir - The langauge directory
host - The host name owning the route for the request
method - The request HTTP method
originalUri - The original, pre-decoded URI
pathInfo - The path portion of the URI after the host and port information
prefix - The route prefix
query - The request query information
reference - The request reference fragment. This is the URI portion after "#"
scheme - The request protocol scheme. E.g. "http"
scriptName - The request script or application name
serverAddress - The server IP address
serverPort - The server port number
uri - The full request URI. May be modified by routes, handlers and filters

Also see httpMakePath for additional tokens (DOCUMENTS_DIR, HOME_DIR, BIN_DIR, PRODUCT, OS, VERSION).

Parameters:

route	Route to modify.
name	Target rule to add. Supported update rules include: "close", "redirect", "run" and "write". The "close" rule is used to do abortive closes for the request. This is useful for ward off known security attackers. For example: "close immediate". The "close" rule takes no addition parameters. The "redirect" rule is used to redirect the request to a new resource. For example: "redirect 302 /tryAgain.html". The "redirect" takes the form: "redirect status URI". The status code is used as the HTTP response code. The URI can be a fully qualified URI beginning with "http" or it can be a relative URI. The "run" target is used to run the configured handler to respond to the request. For example: "file ${DOCUMENTS}/${request.uri}.gz". The "write" rule is used to write literal data back to the client. For example: "write 200 Hello World\r\n". The "write" rule takes the form: "write [-r] status message". Write data is by default HTML encoded to help eliminate XSS security exposures. The "-r" option selects "raw" output and bypasses the HTML encoding of the write data string. WARNING: Take great care when using raw writes with tokens. Write data is not HTML encoded and echoing back to raw data to the client can cause XSS and other security issues. The status field defines the HTTP status code to use in the response.
details	Update rule parameters.

Returns:: "Zero" if successful, otherwise a negative MPR error code.

ssize httpRead (HttpStream *stream, char *buffer, ssize size)

Read rx body data.

Description:: This routine will read body data from the connection read queue (HttpStream.readq) which is at the head of the response pipeline.

This call will block depending on whether the connection is in async or sync mode. Sync mode is the default for client connections and async for server connections.

If in sync mode, this call may block to wait for data. If in async mode, the call will not block and will return with whatever data is available.

In sync mode, this routine may invoke mprYield before blocking to consent for the garbage collector to run. Callers must ensure they have retained all required temporary memory before invoking this routine.

This call will block for at most the timeout specified by the connection inactivity timeout defined in HttpStream.limits.inactivityTimeout. Use httpSetTimeout to change the timeout value.

Server applications often prefer to access packets directly from the connection readq which offers a higher performance interface.

Parameters:

stream	HttpStream stream object created via httpCreateStream
buffer	Buffer to receive read data.
size	Size of buffer.

Returns:: The number of bytes read. Returns zero for not data. EOF can be detected by testing httpIsEof

API Stability:: Stable.

ssize httpReadBlock (HttpStream *stream, char *buffer, ssize size, MprTicks timeout, int flags)

Read a block of rx body data.

Description:: This routine will read body data and provide control over blocking and call duration.

If in blocking mode (the default for client connections), this call may block to wait for data. If in non-blocking mode (the default for server connections), the call will not block and will return with whatever data is available. The blocking mode is set via the flags parameter.

In blocking mode, this routine may invoke mprYield before blocking to consent for the garbage collector to run. Callers must ensure they have retained all required temporary memory before invoking this routine.

This call will block for at most the timeout specified by the connection inactivity timeout defined in HttpStream.limits.inactivityTimeout. Use httpSetTimeout to change the timeout value.

Server applications should not call httpReadBlock in blocking mode as it will consume a valuable thread. Rather, server apps should perform non-blocking reads or access packets directly from the connection readq which offers a higher performance interface.

Parameters:

stream	HttpStream stream object created via httpCreateStream
buffer	Buffer to receive read data.
size	Size of buffer.
timeout	Timeout in milliseconds to wait. Set to -1 to use the default inactivity timeout. Set to zero to wait forever.
flags	Set to HTTP_BLOCK to wait for data before returning. Set to HTTP_NON_BLOCK to read what is available and return without blocking. If set to zero, it will default to HTTP_BLOCK for sync connections and HTTP_NON_BLOCK for async connections.

Returns:: The number of bytes read. Returns zero for not data. EOF can be detected by testing httpIsEof

HttpStage

Pipeline Stages.

Description:: The request pipeline consists of a full-duplex pipeline of stages. Stages are used to process client HTTP requests in a modular fashion. Each stage either creates, filters or consumes data packets. The HttpStage structure describes the stage capabilities and callbacks. Each stage has two queues, one for outgoing data and one for incoming data.

Stages provide callback methods for parsing configuration, matching requests, open/close, run and the acceptance and service of incoming and outgoing data. The order of these callbacks will vary depending if HttpRx.streaming is set. FileUpload requires streaming and the input callback for some stages in the standard pipeline may be invoked before the request is routed.

API Stability:: Internal.

Fields:

void(*	close) (HttpQueue *q)	Close the stage. Description:Close the stage and cleanup any request resources. Handlers may block or yield in this callback. qQueue instance objectAPI Stability:Stable
MprHash *	extensions	Matching extensions for this filter.
int	flags	Stage flags.
void(*	incoming) (HttpQueue q, HttpPacket packet)	Process incoming data. Description:Accept an incoming packet of data. Filters and handlers recieve packets via their incoming callback. They can choose to immediately process or forward the packet, or they can queue the packet on their queue and schedule their incomingService callback for batch processing of all queued packets. This is a common pattern where the incoming routine is not used and packets are automatically queued and the incomingService callback is used to process. Not used by connectors. Stages should not block or yield in this callback. qQueue instance object packetPacket of dataAPI Stability:Stable
void(*	incomingService) (HttpQueue *q)	Service the incoming data queue. Description:This callback should service packets on the queue and process or forward as appropriate. A service routine should check upstream queues by calling httpWillNextQueueAcceptPacket before forwarding packets to ensure they do not overfow upstream queues. Handlers may not block or yield in this callback. qQueue instance objectAPI Stability:Stable
int(*	match) (struct HttpStream stream, struct HttpRoute route, int dir)	Match a request. Description:This routine is invoked to see if the stage wishes to handle the request. For handlers, the match callback is invoked when selecting the appropriate route for the request. For filters, the callback is invoked subsequently when constructing the request pipeline. If a filter declines to handle a request, the filter will be removed from the pipeline for the specified direction. The direction argument should be ignored for handlers. Handlers and filters must not actually handle the request in the match callback and must not call httpError. Errors can be reported via mprError. Handlers can defer error reporting until their start callback. streamHttpStream stream object routeRoute object dirQueue direction. Set to HTTP_QUEUE_TX or HTTP_QUEUE_RX. Always set to HTTP_QUEUE_TX for handlers. HTTP_ROUTE_OK if the request is acceptable. Return HTTP_ROUTE_REROUTE if the request has been rewritten. Return HTTP_ROUTE_REJECT it the request is not acceptable.API Stability:Stable
MprModule *	module	Backing module.
char *	name	Stage name.
int(*	open) (HttpQueue *q)	Open the stage. Description:Open the stage for this request instance. A handler may service the request in the open routine and may call httpError if required. Handlers may block or yield in this callback. qQueue instance object Zero for success. Otherwise a negative MPR error code.API Stability:Stable
void(*	outgoing) (HttpQueue q, HttpPacket packet)	Process outgoing data. Description:Accept a packet as outgoing data. Not used by handlers as handler generate packets internally. Filters will use this entry point to accept outgoing packets. Filters can choose to immediately process or forward the packet, or they can queue the packet on their queue and schedule their outgoingService callback for batch processing of all queued packets. This is a common pattern where the outgoing routine is not used and packets are automatically queued and the outgoingService callback is used to process data. Filters should not block or yield in this callback. qQueue instance object packetPacket of dataAPI Stability:Stable
void(*	outgoingService) (HttpQueue *q)	Service the outgoing data queue. Description:This callback should service packets on the queue and process or forward as appropriate. A service routine should check downstream queues by calling httpWillNextQueueAcceptPacket before forwarding packets to ensure they do not overfow downstream queues. Stages should not block or yield in this callback. qQueue instance objectAPI Stability:Stable
char *	path	Backing module path (from LoadModule).
void(*	ready) (HttpQueue *q)	The request is now fully ready. Description:This callback will be invoked when all incoming data has been received. The ready callback will not be called if the request already has an error. If a handler finishes processing the request, it should call httpFinalizeOutput in the ready routine. Handlers may block or yield in this callback. qQueue instance objectAPI Stability:Stable
int(*	rewrite) (struct HttpStream *stream)	Rewrite a request after matching. Description:This callback will be invoked for handlers after matching and selecting the handler. streamHttpStream stream object Zero for success. Otherwise a negative MPR error code.API Stability:Stable
void *	stageData	Private stage data.
void(*	start) (HttpQueue *q)	Start the handler. Description:The start callback is primarily responsible for starting the request processing. Depending on the request Content Type, the request will be started at different times. Form requests with a Content-Type of "application/x-www-form-urlencoded", will be started after fully receiving all input data. Other requests will be started immediately after the request headers have been parsed and before receiving input data. This enables such requests to stream large quantities of input data without buffering. The start callback should test the HTTP method in stream->rx->method and only respond to supported HTTP methods. It should call httpError for unsupported methods. The start callback will not be called if the request already has an error. Handlers may block or yield in this callback. qQueue instance objectAPI Stability:Stable
void(*	writable) (HttpQueue *q)	The outgoing pipeline is writable and can accept more response data. Description:This callback will be invoked after all incoming data has been receeived and whenever the outgoing pipeline can absorb more output data (writable). As such, it may be called multiple times and can be effectively used for non-blocking generation of a response. The writable callback will not be invoked if the request output has been finalized or if an error has occurred. Handlers may block or yield in this callback. qQueue instance objectAPI Stability:Stable

HttpStream

Http request stream.

Description:

The HttpStream object represents a logical request stream to a peer. A stream object is created for each request transaction. A stream object uses the underlying HttpNet network object. If using HTTP/2 there may be multiple HttpStream objects multiplexed over a single HttpNet object. If using HTTP/1, a single HttpStream object may service many Http requests due to HTTP/1.1 keep-alive.

In prior versions before HTTP/2, this was called the HttpConn (connection) object. For compatibility, a macro define will redefine HttpConn references to HttpStream.

Each connection has a request timeout and inactivity timeout. These can be set via httpSetTimeout. The set of APIs that block and yield to the garbage collector are:

httpFlushQueue(, HTTP_BLOCK)
httpWriteBlock(, HTTP_BLOCK)
httpSendBlock(, HTTP_BLOCK)
httpRead() when in sync mode
httpReadBlock(, HTTP_BLOCK)
httpWait()
httpWriteUploadData

When these APIs block and yield, the garbage collector may reclaim allocated memory that does not have a managed reference. Read Appweb memory allocation at https://embedthis.com/appweb/doc/ref/memory.html.

Some of the HttpStream fields are replicated from the HttpNet object for API compatibility.

int httpCreateEvent (uint64 streamSeqno, HttpEventProc callback, void *data)

Invoke a callback on a stream using a stream sequence number.

Description:: This routine invokes a callback on a stream's event dispatcher in a thread-safe manner. This API is the only safe way to invoke APIs on a stream from foreign threads.

Parameters:

streamSeqno	HttpStream->seqno identifier extracted when running in an MPR (Appweb) thread.
callback	Callback function to invoke. The callback will always be invoked if the call is successful so that you can free any allocated resources. If the stream is destroyed before the event is run, the callback will be invoked and the "stream" argument will be set to NULL. If is important to check the HttpStream.error and HttpStream.state in the callback to ensure the Stream is in an acceptable state for your logic. Typically you want HttpStream.state to be greater than HTTP_STATE_BEGIN and less than HTTP_STATE_COMPLETE. You may also wish to check HttpStream.error incase the stream request has errored.
data	Data to pass to the callback. This is unmanaged data. The caller is responsible for retaining and freeing.

Returns:: "Zero" if the stream can be found and the event is scheduled, Otherwise returns MPR_ERR_CANT_FIND.

void httpDestroyStream (HttpStream *stream)

Destroy the stream object.

Description:: This call closes the connection socket, destroys the connection dispatcher, disconnects the HttpTx and HttpRx property objects and removes the connection from the HttpHost list of connections. Thereafter, the garbage collector can reclaim all memory. It may be called by client connections at any time from a top-level event running on the connection's dispatcher. Server-side code should not need to explicitly destroy the connection as it will be done automatically via httpIOEvent. This routine should not be called deep within the stack as it will zero the HttpStream.http property to signify the connection is destroyed.

Parameters:

stream

HttpStream object created via httpCreateStream

void httpDisconnectStream (HttpStream *stream)

Disconnect the connection's socket.

Description:: This call will close the socket and signal a connection error by setting connError. Subsequent use of the connection socket will not be possible. It will also set HttpRx.eof and will finalize the request. Used internally when a connection times out and for abortive errors. This should not be generally used. Rather, httpDestroyStream and httpError should be used in preference.

Parameters:

stream

void httpError (HttpStream *stream, int status, cchar *fmt, ...)

Error handling for the connection.

Description:: The httpError call is used to flag the current request as failed. If httpError is called multiple times, those calls are ignored and only the first call to httpError has effect. This call will discard all data in the output pipeline queues. If some data has already been written to the client the connection will be aborted so the client can get some indication that an error has occurred after the headers have been transmitted.

Parameters:

stream	HttpStream stream object created via httpCreateStream
status	Http status code. The status code can be ored with the flags HTTP_ABORT to immediately abort the connection or HTTP_CLOSE to close the connection at the completion of the request.
fmt	Printf style formatted string.
...	Arguments for fmt.

void HttpStream * HttpStream * httpFindStream (uint64 seqno, HttpEventProc proc, void *data)

Find a stream given a stream sequence number.

Description:: Find a stream in a thread-safe manner given a stream sequence number. Each stream has a unique 64-bit sequence number that can be used to retrieve a stream object. When using foreign threads, this is preferable as another thread may disconnect and destroy the stream at any time.

A callback may be provided which will be invoked if the stream is found before returning from the API. This should be used if utilizing this API in a foreign thread. httpFindStream will lock the stream while the callback is invoked.

Parameters:

seqno	HttpStream stream sequence number retrieved from HttpStream.seqno.
proc	Callback function to invoke with the signature void (HttpEventProc)(struct HttpStream stream, void *data);.
data	Data to pass to the callback.

Returns:: The steam object reference. Returns NULL if the stream is not found. Only use this value if invoked in an MPR thread. While foreign threads using this API may return a stream reference, the stream may be destroyed before the reference can be used.

void httpSetKeepAliveCount (HttpStream *stream, int count)

Control Http Keep-Alive for the connection.

Description:: Http Keep-Alive means that the TCP/IP connection is preserved accross multiple requests. This typically means much higher performance and better response. Http Keep-Alive is enabled by default for Http/1.1 (the default). Disable Keep-Alive when talking to old, broken HTTP servers.

Parameters:

stream	HttpStream stream object created via httpCreateStream
count	Count of Keep-Alive transactions to use before closing the connection. Set to zero to disable keep-alive.

Description:: The connection states are, in order : HTTP_STATE_BEGIN HTTP_STATE_CONNECTED HTTP_STATE_FIRST HTTP_STATE_PARSED HTTP_STATE_CONTENT HTTP_STATE_READY HTTP_STATE_RUNNING HTTP_STATE_FINALIZED HTTP_STATE_COMPLETE. When httpSetState advances the state it will invoke any registered HttpNotifier. If the state is set to a state beyond the next intermediate state, the HttpNotifier will be invoked for all intervening states. This is true even if the request has no content, the HTTP_STATE_CONTENT will still be visited.

HTTP_EVENT_STATE The request is changing state. Valid states are: HTTP_STATE_BEGIN, HTTP_STATE_CONNECTED, HTTP_STATE_FIRST, HTTP_STATE_CONTENT, HTTP_STATE_READY, HTTP_STATE_RUNNING, HTTP_STATE_FINALIZED and HTTP_STATE_COMPLETE. A request will always visit all states and the notifier will be invoked for each and every state. This is true even if the request has no content, the HTTP_STATE_CONTENT will still be visited.
HTTP_EVENT_READABLE There is data available to read
HTTP_EVENT_WRITABLE The outgoing pipeline can absorb more data. The WRITABLE event is issued when the outgoing pipeline is empties and can absorb more data.
HTTP_EVENT_ERROR The request has encountered an error
HTTP_EVENT_DESTROY The HttpStream object is about to be destoyed
HTTP_EVENT_APP_OPEN The application layer is now open
HTTP_EVENT_APP_CLOSE The application layer is now closed

Log (trace) an event of interest.

Description:: The Http trace log is for operational request and server messages and should be used in preference to the MPR error log which should be used only for configuration and hard system-wide errors.

Parameters:

trace	HttpTrace object. Typically used via HttpStream.trace or HttpNet.trace.
event	Event name to trace. Typically dot separated module names.
type	Event type to trace. Events are grouped into types that are traced at the same level.

HttpPacket * * httpCreateHeaders (HttpQueue *q, HttpPacket *packet)

Create a HTTP header packet.

Description:: Write the Http transmission headers into the given packet. This should only be called by connectors just prior to sending output to the client. It should be delayed as long as possible if the content length is not yet known to give the pipeline a chance to determine the transmission length. This way, a non-chunked transmission can be sent with a content-length header. This is the fastest HTTP transmission.

void httpFinalize (HttpStream *stream)

Indicate the request is finalized.

Description:: Calling this routine indicates that the handler has fully finished processing the request including processing all input, generating a full response and any other required processing. This call will invoke httpFinalizeOutput and then set the request finalized flag. If the request is already finalized, this call does nothing. A handler MUST call httpFinalize when it has completed processing a request. As background: there are three finalize concepts: HttpTx.finalizedOutput means the handler has generated all the response output but it may not yet be fully transmited through the pipeline and to the network by the connector. HttpTx.finalizedConnector means the connector has sent all the output to the network. HttpTx.finalized means the application has fully processed the request including reading all the input data it wishes to read and has generated all the output that will be generated. A fully finalized request has both HttpTx.finalized and HttpTx.finalizedConnector true.

Parameters:

stream

HttpStream stream object.

Parameters:

stream

HttpStream Queue object.

API Stability:: Stable.

void httpFinalizeOutput (HttpStream *stream)

Finalize transmission of the http response.

Description:: This routine should be called by applications and handlers to signify the end of the body content being sent with the request or response body. This call will force the transmission of buffered content to the peer. HttpFinalizeOutput will set the HttpTx.finalizedOutput flag and write a final chunk trailer if using chunked transfers. If the output is already finalized, this call does nothing. Note that after finalization, incoming content may continue to be processed. i.e. httpFinalizeOutput can be called before all incoming data has been received. Use httpFinalizeInput to signify that processing all input is complete.

The difference between httpFinalize and httpFinalizeOutput is that httpFinalize implies that all request processing is complete including both input and output. Whereas httpFinalizeOutput implies that the output is generated. Note that while the output may be fully generated, it may not be fully transmitted by the pipeline and connector. When the output is fully transmitted, the connector will call httpFinalizeConnector

Parameters:

stream

HttpStream Queue object.

void httpFlushAll (HttpStream *stream)

Flush transmit data and wait for all the data to be written to the socket.

Description:: This call initiates writing buffered data. If in sync mode this call may block until the output queues drain. In sync mode, this may invoke mprYield before blocking to consent for the garbage collector to run. Callers must ensure they have retained all required temporary memory before invoking this routine. Filters and connectors should not call this routine as it may block. Use httpFlush in filters or connectors. Handlers may only call this routine in their open, close, ready, start and writable callbacks. See httpFlush if you do need to wait for all the data to be written to the socket.

Set a transmission cookie.

Description:: Define a cookie to send in the transmission Http header.

Parameters:

stream	HttpStream stream object created via httpCreateStream
name	Cookie name.
value	Cookie value.
path	URI path to which the cookie applies.
domain	Domain in which the cookie applies. Must have 2-3 dots. If null, a domain is created using the current request host header. If set to the empty string, the domain field is omitted. If the domain is a numerical IP address or localhost, the domain will not be included as the browsers do not support this pattern consistently. Note that hostname port numbers are ignored by browsers and so web sites with the same domain name but different port numbers may have conflicting cookies. This is according to the Cookie RFC standard.
lifespan	Duration for the cookie to persist in msec. Set to zero to create a session cookie that is meant to be automatically removed when the user exits their browser. However, beware, Chrome subverts this and will persist session cookies if "Continue where you left off" is enabled in Chrome preferences.
flags	Cookie options mask. The following options are supported: HTTP_COOKIE_SECURE - Set the 'Secure' attribute on the cookie. HTTP_COOKIE_HTTP - Set the 'HttpOnly' attribute on the cookie. HTTP_COOKIE_SAME_LAX - Set the 'SameSite=Lax' attribute on the cookie. HTTP_COOKIE_SAME_STRICT - Set the 'SameSite=Strict' attribute on the cookie. See RFC 6265 for details about the 'Secure' and 'HttpOnly' cookie attributes.

bool httpSetFilename (HttpStream *stream, cchar *filename, int flags)

Set the filename to serve for a request.

Description:: This routine defines a non-default response document filename. The filename may be virtual and not correspond to a physical file. It also may be a file outside the documents root directory. If it is not a file under the route documents directory, set the flags parameter to HTTP_TX_NO_CHECK. Otherwise, the filename will be checked to ensure it is inside the route documents directory.

Typically a handler will call httpMapFile to perform default request URI to filename mapping and should not need to call httpSetFilename unless a file outside the route documents directory is required to be served.

This routine will set the HttpTx filename, ext, etag and fileInfo fields.

Note: the response header mime type will be set based on the request URI. To override, use httpSetContentType

Parameters:

stream	HttpStream stream object.
filename	Tx filename to define. Set to NULL to reset the filename.
flags	Flags word. Or together the desired flags. Include to HTTP_TX_NO_CHECK to bypass checking if the filename resides inside the route documents directory.

int httpWait (HttpStream *stream, int state, MprTicks timeout)

Wait for the client connection to achieve the requested state.

Description:: This call blocks until the connection reaches the desired state. It creates a wait handler and services events while waiting. This is useful for blocking client requests, and should never be used on server-side connections.

It is often required to call mprStartDispatcher on the connection dispatcher after calling $httpCreateStream. This ensures that all foreground activity on the connection is serialized with respect to work done in response to I/O events while waiting in httpWait.

This routine may invoke mprYield before it sleeps to consent for the garbage collector to turn. Callers must ensure they have retained all required temporary memory before invoking this routine.

Parameters:

stream	HttpStream stream object created via httpCreateStream
state	HTTP_STATE_XXX to wait for.
timeout	Timeout in milliseconds to wait. Set to -1 to use the default connection timeouts. Set to zero to wait forever.

Returns:: "Zero" if successful. Otherwise return a negative MPR error code. Specific returns include: MPR_ERR_TIMEOUT and MPR_ERR_BAD_STATE.

char * * httpLink (struct HttpStream *stream, cchar *target)

Create a URI link.

Description:: Create a URI link based on a given target relative to the current request. This API expands embedded tokens based on the current request and route state. The target URI parameter may contain partial or complete URI information. The missing parts are supplied using the current request and route tables.

Parameters:

stream

HttpStream stream object.

target

The URI target. The target parameter can be a URI string or JSON style set of options. The target will have any embedded "{tokens}" expanded by using token values from the request parameters. If the target has an absolute URI path, that path is used directly after tokenization. If the target begins with "~", that character will be replaced with the route prefix. This is a very convenient way to create application top-level relative links.

If the target is a string that begins with "{AT}" it will be interpreted as a service/action pair of the form "{AT}Service/action". If the "service/" portion is absent, the current service is used. If the action component is missing, the "list" action is used. A bare "{AT}" refers to the "list" action of the current service.

If the target starts with "{" it is interpreted as being a JSON style set of options that describe the link. If the target is a relative URI path, it is appended to the current request URI path.

If the is a JSON style of options, it can specify the URI components: scheme, host, port, path, reference and query. If these component properties are supplied, these will be combined to create a URI.

If the target specifies either a service/action or a JSON set of options, The URI will be created according to the route URI template. The template may be explicitly specified via a "route" target property. Otherwise, if an "action" property is specified, the route of the same name will be used. If these don't result in a usable route, the "default" route will be used.

These are the properties supported in a JSON style "{ ... }" target:

scheme String URI scheme portion
host String URI host portion
port Number URI port number
path String URI path portion
reference String URI path reference. Does not include "#"
query String URI query parameters. Does not include "?"
service String Service name if using a Service-based route. This can also be specified via the action option.
action String Action to invoke. This can be a URI string or a Service action of the form {AT}Service/action.
route String Route name to use for the URI template

Returns:: A normalized Uri string.

HttpWebSocket

WebSocket Service to implement the WebSockets RFC 6455 specification for client and server communications.

Description:: WebSockets is a technology providing interactive communication between a server and client. Normal HTML connections follow a request / response paradigm and do not easily support asynchronous communications or unsolicited data pushed from the server to the client. WebSockets solves this by supporting bi-directional, full-duplex communications over persistent connections. A WebSocket connection is established over a standard HTTP connection and is then upgraded without impacting the original connection. This means it will work with existing networking infrastructure including firewalls and proxies.

ssize httpSendBlock (HttpStream *stream, int type, cchar *msg, ssize len, int flags)

Send a message of a given type to the WebSocket peer.

Description:: This is the lower-level message send routine. It permits control of message types and message framing.

This routine can operate in a blocking, non-blocking or buffered mode. Blocking mode is specified via the HTTP_BLOCK flag. When blocking, the call will wait until it has written all the data. The call will either accept and write all the data or it will fail, it will never return "short" with a partial write. If in blocking mode, the call may block for up to the inactivity timeout specified in the stream->limits->inactivityTimeout value.

Non-blocking mode is specified via the HTTP_NON_BLOCK flag. In this mode, the call will consume that amount of data that will fit within the outgoing WebSocket queues. Consequently, it may return "short" with a partial write. If this occurs the next call to httpSendBlock should set the message type to WS_MSG_CONT to indicate a continued message. This is required by the WebSockets specification.

Buffered mode is the default and may be explicitly specified via the HTTP_BUFFER flag. In buffered mode, the entire message will be accepted and will be buffered if required.

This API may split the message into frames such that no frame is larger than the limit stream->limits->webSocketsFrameSize. However, if the HTTP_MORE flag is specified to indicate there is more data to complete this entire message, the data provided to this call will not be split into frames and will not be aggregated with previous or subsequent messages. i.e. frame boundaries will be presserved and sent as-is to the peer.

In blocking mode, this routine may invoke mprYield before blocking to consent for the garbage collector to run. Callers must ensure they have retained all required temporary memory before invoking this routine.

Parameters:

stream	HttpStream stream object created via httpCreateStream
type	Web socket message type. Choose from WS_MSG_TEXT, WS_MSG_BINARY or WS_MSG_PING. Use httpSendClose to send a close message. Do not send a WS_MSG_PONG message as it is generated internally by the Web Sockets module. If using HTTP_NON_BLOCK and the call returns having written only a portion of the data, you must set the type to WS_MSG_CONT for the.
msg	Message data buffer to send.
len	Length of msg.
flags	Include the flag HTTP_BLOCK for blocking operation or HTTP_NON_BLOCK for non-blocking. Set to HTTP_BUFFER to buffer the data if required and never block. Set to zero will default to HTTP_BUFFER. Include the flag HTTP_MORE to indicate there is more data to come to complete this message. This will set frame continuation bit. Setting HTTP_MORE preserve the frame boundaries. i.e. it will ensure the data written is not split into frames or aggregated with other data.

Returns:: Number of data message bytes written. Should equal len if successful, otherwise returns a negative MPR error code.

ssize httpSendClose (HttpStream *stream, int status, cchar *reason)

Send a close message to the WebSocket peer.

Description:: This call invokes httpSendBlock with a type of WS_MSG_CLOSE and flags of HTTP_BUFFER. The status and reason are encoded in the message. The reason is an optional UTF8 closure reason message.

Parameters:

stream	HttpStream stream object created via httpCreateStream
status	Web socket status.
reason	Optional UTF8 reason text message. The reason must be less than 124 bytes in length.

Returns:: Number of data message bytes written. Should equal len if successful, otherwise returns a negative MPR error code.

void httpSetWebSocketPreserveFrames (HttpStream *stream, bool on)

Preserve frames for incoming messages.

Description:: This routine enables user control of message framing. When preserving frames, sent message boundaries will be preserved and will not be split into frames or aggregated with other message frames. Received messages will similarly have their frame boundaries preserved and will be stored one frame per HttpPacket. Note: enabling this option may prevent full validation of UTF8 text messages if UTF8 codepoints span frame boundaries.

Parameters:

stream	HttpStream stream object created via httpCreateStream
on	Set to true to preserve frames.
