I read the thread, you said:

"Obviously, one can edit every template file to make sure the URL has the
application's prefix.
But it's an ugly hard-coded solution, and requires synchronization between
the perl code's "prefix" and the template's hardocded URLs.

I want an application-wide "prefix" setting (in the config file, or
similar), that would affect every part of the application."

I think your best option is to either make your own config variable and put
that in every template.  You don't have to synchronize the templates and
prefix setting, you only have to synchronize the new config variable you
make and the prefix setting.
