I am running a modified web server example. Beyond sending HTML to the client once the web server IP is hit from the browser, I want the web server to be able to send HTML based on data coming from the client. For example: if the client uses http://IPAddress/message1 then the web server will send Message 1 if the client uses http://IPAddress/message2 then the webserver will send message 2. Alternatively find another way to send data from the client (browser) to the web server. Any ideas?
