Internet Explorer Caching - Solved

I've been having problems with Internet Explorer caching php programs. I'm using the following code:

       header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
       header("Pragma", "no-cache");
       header("Expires", "-1");

And it used to work, but now, according to Windows Explorer its giving it 3 hours to expire. Charlene I am using sessions, and it appears to work differently in PHP5 than PHP4 (not fully tested as to verification of that statement). So I needed to add a line of code before the session_start function:

session_cache_expire(0); session_start(); Charlene
