[snip] Essentially, I'm looking to write something in the same vein as GNU httptunnel, but in PHP, and running on port 80 serverside. [/snip] All of that was nice, but still does not explain what you are trying to accomplish other than maintaining a connection state between client and server. What kind of process are you running that would require this? That is what I am looking for. What is the real issue? What would you do that would require a stated connection? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
