Tool/software: TI-RTOS
I Just started to work on HTTP server for Tm4c1294 board by looking into . I created a simple Application to create a HTTP webserver . I have a code which I am posting

I have added the two cgis for turning the LED on and OFF.
My html code is in below
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "www.w3.org/.../strict.dtd"> <html><head><meta content="text/html; charset=ISO-8859-1" http-equiv="content-type"><title>Concerto HTTP Server</title></head> <body>Hello World<br> <br>Click To Turn LED ON <a href="LEDON.cgi">LEDON.cgi</a><br> <br>Click To Turn OFF <a href="LEDOFF.cgi">LEDOFF.cgi</a><br> </body></html>
Here is my webserver. Now i want to create a webserver with ON and OFF buttons rather than this.. I dont want to go to next webpage which is happening here. What to refer to achieve this ..I mean button creation .
