If you are using mod_perl it's really easy if you set up a
CGI::Application::Dispatch and then set up apache like this:
   <Perl>
      use lib 'path/to/lib';
   </Perl>
   <Location /acdri>
      SetHandler perl-script
      PerlHandler ACD::Dispatch
   </Location>

Then you should be able to set headers the regular cgiapp way.
