PHP as MODULE & CGI Version of PHP

I was going through this fantastic tutorial on HTTP Authentication at Zend.com! It mentioned that to have this working, PHP must be "Installed as a Module" and NOT as "CGI Version". Because it will not work in CGI version. Tell me something, how and from where can i install PHP as a Module on my system? I'm using a PWS (Personal Web Server) on my Windows 98 machine. I had downloaded PHP from the php.net site and installed as per the instructions in the manual. What is the difference between the Module & CGI version? Is it possible for me to Install PHP as module on my computer? Regards, T. Edison jr. ===== Rahul S. Johari (Director) ****************************************** Abraxas Technologies Inc.
