Really? I'm *so* glad that there are good templating solutions out 
there. Separating the content from the code is a godsend. Being able to 
edit a template with an HTML editor or not having to mess around in my 
perl code for small (or even large) formatting changes is so nice. Maybe 
one day we'll help you see the light :)

Besides, don't you consider using an HTML page with SSI to be a 
template? If that's all you are doing, then it's pretty much 
HTML::Template with a different syntax.

I also noticed your post about using Class:DBI (which I assume is for 
the same project). Using the Model-View-Controller pattern with 
Class::DBI as the model, CGI::App as the controller, and TT or 
HTML::Template as the view really helps me to organize large projects 
and keep a good separation of concerns.

This is really a downside of using SSI like that for multiple CGI's. If 
you are using vanilla cgi (not mod_perl) then your server will not only 
have to spawn a perl process for each request, but multiple perl 
processes per request and that can really slow things down. This is one 
of the reasons I suggested using a templating system. It would all be 
within one process. Even under mod_perl this system would be faster than 
SSI.
