If you are familiar with the structure and features of ASP, then I would recommend looking at Apache::ASP. This is a framework that has borrowed the good things from ASP and added a lot more as well. A quote from the Apache::ASP website:

Apache::ASP provides an Active Server Pages port to the Apache Web Server with Perl scripting only, and enables developing of dynamic web applications with session management and embedded Perl code. There are also many powerful extensions, including XML taglibs, XSLT rendering, and new events not originally part of the ASP API!

It won't be possible to copy your ASP code exactly, but it should be easy enough to translate it.
