Parameters:

proc	Function of the type HttpConfigureProc.
arg	Reference argument to pass to the callback proc. Can be a managed or an unmanaged reference.
timeout	Timeout in milliseconds to wait. Set to -1 to use the default server inactivity timeout. Set to zero to wait forever.

Description:: This defines the login form URL and login/out service URLs. Set arguments to null if they are not required because the application is implementing its own redirection management during login. This API should not be used for web frameworks like ESP or PHP that define their own login/out services.

Parameters:

route	Route from which to inherit when creating a route for the login pages and services.
loginPage	Web page URI for the user to enter username and password.
loginService	URI to use for the internal login service. To use your own login URI, set to this the empty string.
logoutService	URI to use to log the user out. To use your won logout URI, set this to the empty string.
loggedInPage	The client is redirected to this URI once logged in. Use a "referrer:" prefix to the URI to redirect the user to the referring URI before the loginPage. If the referrer cannot be determined, the base URI is utilized.
loggedOutPage	The client is redirected to this URI once logged in. Use a "referrer:" prefix to the URI to redirect the user to the referring URI before the loginPage. If the referrer cannot be determined, the base URI is utilized.

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.

Returns:: A count of the bytes actually written.

void httpBorrowNet (HttpNet *net)

Borrow a network connection.

Description:: Borrow the network from Http. This effectively gains an exclusive loan of the network so that it cannot be destroyed while the loan is active. After the loan is complete, you must call return the network by calling httpReturnNet. Otherwise the network will not be freed and memory will leak.

The httpBorrowNet routine is used to stabilize a network while interacting with some outside service. Without this routine, the network could be destroyed while waiting. Many things can happen while waiting. For example: the client could disconnect or the network connection could timeout. These events will still be serviced while the network is borrowed, but the network object will not be destroyed.

While borrowed, you must not access the network object using foreign / non-MPR threads. If you need to do this, use mprCreateEvent to schedule an event to run on the networks's event dispatcher. This is essential to serialize access to the network object.

Before returning from the event callback, you must call httpReturnNet to end the exclusive loan. This restores normal processing of the connection and enables any required I/O events.

Parameters:

net	HttpNet object created via httpCreateNet

API Stability:: Internal.

int httpConnectNet (HttpNet *net, cchar *ip, int port, MprSsl *ssl)

Connect the network to a remote peer.

Parameters:

net	HttpNet Network object created via httpCreateNet
ip	Remote IP address to connect to.
port	TCP/IP port to connect to.
ssl	MprSsl object that defines the SSL context.

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

HttpNet * httpCreateNet (MprDispatcher *dispatcher, struct HttpEndpoint *endpoint, int protocol, int flags)

Create a network object.

Description:: The network object defines the underlying network connection over which HttpStream connection streams will be multiplexed.

Parameters:

dispatcher	Event MprDispatcher object to serialize events for the network.
endpoint	Server-side HttpEndpoint object. Set to NULL for client-side.
protocol	HTTP protocol to use by default. Set to 1 for HTTP/1 and 2 for HTTP/2.
flags	Set to HTTP_NET_ASYNC if you wish to use async I/O. Otherwise set to zero.

Returns:: A new network object.

void httpDestroyNet (HttpNet *net)

Destroy the network object.

Description:: This call closes the network socket, destroys the connection dispatcher, disconnects the HttpStream objects and removes the network from the HttpHost list of networks. All active stream connections (HttpStream) will also be destroyed. 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 explicitly destroy the connection as it will be done automatically via httpIOEvent.

Parameters:

net	HttpNet object created via httpCreateNet

API Stability:: Internal.

void httpEnableNetEvents (HttpNet *net)

Enable network events.

Description:: Network events are automatically disabled upon receipt of an I/O event on a network connection. This permits a network to process the I/O without fear of interruption by another I/O event. At the completion of processing of the I/O request, the network should be re-enabled via httpEnableNetEvents. This call is made for requests in httpIOEvent. Client-side networks may need to enable network events if they are running in async mode and encounter a blocking condition.

Parameters:

net	HttpNet Network object created via httpCreateNet

void httpNetError (HttpNet *net, cchar *fmt, ...)

Error handling for the network.

Description:: The httpNetError call is used to flag the current network as failed. If httpNetError is called multiple times, those calls are ignored and only the first call to httpNetError has effect. This call will close all network streams and discard all data in output pipeline queues.

void httpReturnNet (HttpNet *net)

Return a borrowed a network connection.

Description:: Returns a borrowed network object back to the Http engine. This ends the exclusive loan of the network so that the current request can be completed. It also enables I/O events based on the current state of the network.

While the network is borrowed, you must not access the network using foreign / non-MPR threads. Use mprCreateEvent to schedule an event to run on the network's event dispatcher. This is essential to serialize access to the network object.

MprSocket * httpStealSocket (HttpNet *net)

Steal a socket from a network.

Description:: Steal the MprSocket object from a network so the caller can assume total responsibility for the socket. This routine returns a clone of the networks's socket object with the socket O/S handle. The handle is removed from the networks's socket object. The network retains ownership of the original MprSocket object sans the socket handle. This is done to preserve the HttpNetwork.sock object but remove the socket handle from its management.

Note: All current streams are aborted and queue data is discarded. After calling, the normal Appweb request and inactivity timeouts will not apply to the returned socket object. It is the callers responsibility to call mprCloseSocket on the returned MprSocket when ready.

HttpPacket

Packet object.

Description:: The request/response pipeline sends data and control information in HttpPacket objects. The output stream typically consists of a HEADER packet followed by zero or more data packets and terminated by an END packet. If the request has input data, the input stream consists of one or more data packets followed by an END packet.

Packets contain data and optional prefix or suffix headers. Packets can be split, joined, filled, or emptied. The pipeline stages will fill or transform packet data as required.

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.

Parameters:

q	Queue to flush.
flags	If set to HTTP_BLOCK, this call will block until the data has drained through the network connector.

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 block 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.

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

Parameters:

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

Returns:: A count of the bytes actually written.

Parameters:

route	Route to modify.
name	Condition rule to add. Supported conditions are: "auth", "missing", "directory", "exists", and "match". The "auth" rule is used internally to implement basic and digest authentication. The "missing" rule tests if the target filename is missing. The "missing" rule takes no arguments. The "directory" rule tests if the condition argument is a directory. 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.
