You can use them all, Apache, IIS, even Personal Webserver, Sambar, Netscape Enterprise, you name it. (almost) every webserver supports CGI. So you still can use Perl (with for instance Activestate's ActivePerl, which is just normal Perl, ported to the windows platform).

But if you mean you have to use ASP on Internet Information Server (IIS) from Microsoft, you can still use Perlscript as the ASP language. This comes with the Activestate Perl distribution.
