include_path in php.ini

I am new to installing and configuring php especially on a windowzzz server. I am having trouble getting php includes to work. example: (<?php include("http://mywebsite.com/forum/ssi.php"); ?>) I get this error: Warning: Failed opening 'http://mywebsite.com/forum/ssi.php'for inclusion (include_path='D:\Inetpub\NewIntraRoot') in D:\Inetpub\NewIntraRoot\test.php on line 6 I know the include path is wrong but I've tried so many different paths. I've searched the php manual but it doesnt give me a good understanding of what really needs to be configured and how to do it. I have also searched the web. It's probobly so simple that it doesnt need any more explanation. Could someone out there give me any advice? System Windows NT 5.0 build 2195 Build Date Sep 6 2002 10:38:51 Server API CGI Virtual Directory Support enabled Configuration File (php.ini) Path C:\WINNT\php.ini Debug Build no Thread Safety enabled implicit_flush Off Off include_path D:\Inetpub\NewIntraRoot D:\Inetpub\NewIntraRoot log_errors Off Off php is installed on C but the site is hosted on D. Does this make sense? Thank you Paul
