James-Brown:
Well it doesn't seem to work.I can format a POST command on my Ethernet Arduino and it does wake up my little PHP script on my Apache server but the $_POST Variable is empty.
I think its because I have not generated a 'Submit' command the way a submit button does from a web page.Any other ideas?
What request are you actually generating? You could either log it within the webserver, or use WireShark or similar, or print it out of the Arduino. Are you setting the Content-Type and Content-Length headers correctly? Have you tried simply URL encoding the request parameters?
