Hi Bert
The best thing to read is the following:
http://www.utasker.com/forum/index.php?topic=94.0This explains the basics about interaction between the web server and the application (this tends to take place in the file webinterface.c, which is a file belonging to the application and not the TCP/IP stack).
This also works very well in the uTasker simulator so it is easy to experiment and test new code. Once it is doing what you want from it you can load it to the real target and it will almost certainly work exactly the same.
Good luck
Regards
Mark
