serverFrame.submit()

s.submit()
This sends the serverFrame to the WebServer specified by "setServerURL()", along with all defined CGI variables. The results will be sent back to the serverFrame specified by "setTarget()". If no target was specified, the results will be sent back to the originating serverFrame, overwriting everything that was in there. See the User's Guide 5.1, for a PHP example how to echo back all submitted variables.
