If they add:

LoadModule perl_module modules/libperl.so
AddModule mod_perl.c

and add:
SetHandler perl-script
PerlHandler Apache::Register
Options +ExecCGI

in my Virtual Host setup, would I need access to the config file for anything else.

I don't know what the chances are of getting them to do this, but I would still like to know if the is all that is needed for me to use mod_perl in my HTML files.

Thanks

I think it's unlikely that they'd go for it.

As well as the above, they need to recompile Apache with mod_perl. It's also conceivable that you might want to use different apache handlers later on, requiring changes to the configuration file.

There's also security problems, you could potentially crash apache and bring down all the sites on the machine, etc.
