Ah, I was under the impression that the IP would be changed if the internet connection was broken, not between page requests. Since VeriSign will not produce a dynamic URL (one containing some sort of session or identification information), I will probably have to fall back on user input if the ip is new and/or not recognized.

I don't really know the answer, but HTTP is not a session-oriented protocol. Each request is independent of all other requests (HTTP 1.1 allows reusing connections to a certain extent, but not for the purposes of maintaining a session). Between a change of pages, the TCP connection is torn down and built back up, so the IP is subject to change. AOL may be using a pool of proxies and handing his requests off to different proxies in a load-balancing scheme. The point is, you can't reliably use REMOTE_ADDR for session management. You've got to pass some kind of data back and forth in the request and response themselves. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
