Coder experienced with HTMLDOC and PHP

I have a PHP script which converts HTML to PDF using HTMLDOC and it is working perfectly to convert sites. The problem I am having is my site requires users be logged in using SESSION. session_start(); if(!$_SESSION['LoginUserId']){ header("location: [login to view URL]"); exit; } I am looking for a way for HTMLDOC to bypass this without using GET. HTMLDOC allows sending of cookies but I am unsure on how to use it. I am using the following passthru $passthru = "htmldoc --quiet --landscape \ --left 0.5in --right 0.5in --header t.D --jpeg 100 --no-compression \ --footer ./. --size a4 -t pdf14 --fontsize 9 \ --webpage ".$filename; ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
