PHP4.2.2 Windows

Hi, I've got a local test machine running WinXP Pro SP1 with PHP 4.2.2 and Apache 1.3.26. What I'd like to do is change the include_path settings for PHP in a .htaccess file (as I have several sites being tested on this machine and do not wish to have to edit the php.ini in my Windows directory each time I switch sites). I've made this work under several flavors of Unix, but not under Windows - does the Windows version of Apache not support .htaccess? Here is the command I'm using: php_value include_path ".;D:\WebPages\2002\www.site.com\docs\" now under Unix it works by doing the following: php_value include_path ".:/client/site/docs" Is there some little step that I've completely missed? Thanks -Tim
