Questions and Answers

Where did GoAhead come from?

The GoAhead embedded HTTP server was originally written by Embedthis staff when working at GoAhead Software in 1998 and GoAhead remains very popular to this day. With the acquisition of GoAhead Software Inc. by Oracle, Oracle asked Embedthis to support existing GoAhead customers and to provide ongoing development and commercial licenses for the GoAhead embedded web server.

How does the GoAhead compare with Appweb?

GoAhead is a simple, compact web server that is ideal for small devices without much memory. It is easily ported and has been ported to many embedded operating systems. Appweb is faster and more powerful — and has more extensive security facilities. If you need a simple, low end web server and have little memory available, then GoAhead is ideal.

Is Embedthis enhancing the GoAhead Embedded Web Server?

Yes. Embedthis is continuing to develop GoAhead and has released a major upgrade in GoAhead version 5. We have applied some of the innovations from Appweb to GoAhead to improve security, functionality and performance.

I have products based on GoAhead 2.1. How can I upgrade?

We have released a special security update version GoAhead 2.2. This is designed to provide an easy transition path toward GoAhead 5. It provides fixes for all known security issues and bugs while maintaining 100% API compatibility with GoAhead 2.1.8. Read more at GoAhead 2 Security Update or contact sales@embedthis.com.

Does GoAhead run on VxWorks?

User Comments

Here are some comments from GoAhead users.

"I've looked at the source code and love it. Very crisp and to the point, no fluff. Well structured, great data structures, very portable, clearly the product of an expert programmer."

— Dwight Vandenberghe, Pentasoft Corporation

"We have carefully evaluated several existing open source Web servers suitable for development. The GoAhead embedded web server was by far the best solution. We managed to port it to ChorusOs and RTEMS in a few hours. That's the proof of a good design and careful coding. Wish your company all the best. Thanks for opening the code."

— Eric Valette Canon

"I've compiled GoAhead embedded web server on a number of platforms (vxWorks, Linux, Windows NT and LynxOS) and been highly impressed by the simplicity and speed of installation. We use the platforms mentioned above for data acquisition systems in science experiments; your product could provide an ideal method for simple monitoring and control of elements of the system. The small footprint and straightforward scripting capabilities are ideal for such applications."
