How to find GET variables when using fopen()?

[Anon]

I'm trying to access another website but when I go to it it automatically redirects me to another URL and assigns me a USERID that time expires.

For example, i open up the page http://www.foo.com and the site automatically redirects me to http://www.foo.com?userid=12345

I need to figure out the GET variable "userid" to do what I want to do. Is there a way to do this when using fopen or fsockopen?

Hi,

Yes it is. Most likely the server sends you a location-statement in the http-header. Open a socket to port 80 on the host and send the string "GET / HTTP1.1\n\n" without the quotes. If you want to play around without writing any code you can try "telnet www.foo.com 80" in your favourite shell.
