Here's how I managed to solve it
my $subr = $r->lookup_uri( $redirect );
$subr->add_output_filter( My::Filter::build_handler( $cgi, $messages ) );
build_handler returns a sub which expects to be used like a filter.
This way I can build this sub with request-specific information for
altering the html generated by the subrequest.
