Mod_Perl -- A very basic question to get started

[RArul]

Hello Friends,

I have all the web-development done in ASP for W2K with IIS Web-Servers and
am a newbie to mod_perl. I have a very basic question on this Perl
technology. Here it is:

         What is the primodial or **chief use** of mod_perl with apache? 
                --Is it to run CGI Scripts under Apache::Registry handler
and just create your own Apache-Handlers on a needed              basis, or 
                -- should the focus be to build all the webpages of the
application as Apache-Handlers and not as CGI Scripts              running
under Apache::Registry?

Thanks,
Rex
