  27. 0?0=Toggle+LED1 Overview: This function is a "callback" from HTTPServer task. Whenever a remote node performs interactive task on page that was served, HTTPServer calls this functions with action arguments info. Main application should interpret this argument and act accordingly. Following is the format of argv: If HTTP action was : thank.htm?name=Joe&age=25 argv[0] => thank.htm argv[1] => name argv[2] => Joe argv[3] => age argv[4] => 25
