Is there difference between Ap. ASP and Win. ASP?

Yes, the Apache one, which I think is called is Chilisoft ASP or something only partly implements ASP and I heard people say that it's crap. Just go with the default IIS ASP if you can

I just figured I'd give you another response...I agree with Zef.

It is Chilisoft, it doesn't fully implement ASP, it's hardly ever updated for the bugs that are currently known, and according to a network admin at my work (who can't always be trusted) the Chilisoft ASP project is all but dead. (I thought it was still kicking, but no where near as good as regular IIS ASP.)

If you want to use ASP.NET and you're on Windows, you can use mod_aspdotnet with Apache. See the 'cli .NET' subproject of the Apache httpd project.

What about mod_mono ? I don't know much about it myself, but I've heard that you can use ASP.NET with Mono and mod_mono.

You can but the mono implementation is probably incomplete and not as good as the MS implemtation.

If you're on linux I guess you could use it though. But if you're on windows it makes no sense not to use mod_aspdotnet instead.
