Mod_Perl is available for Windows. If you take the default Windows Apache binary, and the ActiveState Perl build, you will find that Randy Kobes has built pre-complied mod_Perl for you, and all you need do is configure your PPM for his server, and install it. See perl.apache.org for details.

This does work fine but there are a few things to watch out for in the install, so read the instructions carefully. If all else fails, you can email Randy, he is a very helpful chap, or try one of the many mailing lists or this place for help.

Alas mod_Perl on NT/Apache has some limitations (see multithreading mod_perl on Windows NT), that should go away when Apache 2 is released.

You can also build Apache and Perl on CygWin, and then install mod_Perl as per normal. While this works fine, Apache on Cygwin is about 30% slower than the native NT port, but it's more Unix like.

If you are not running Apache on NT, there are other embedded Perl technologies alailable, including the ActiveState Perl for ISAPI, PerlEx and PerlScript.

Hope this helps.
