Simulating the browser in POST

[LT CASEY RYBACK]

Hi, there is a website where you can sign peoples guestbook.I setup live HTTP headers, and seen what the browser sent. When I try it it doesn't work. I've been at this for ages. Could anyone tell me the best way to do this in PHP? It uses a session ID, a user IDm a login id, and cookies (which are sent with the headers. I'd like to know what do I have to send. Here's a recording:
