You are correct.  SSIs only work when the server reads the page, not when
the page is being generated by a CGI.

Well, almost the same, but to avoid the while loop, you can either do:

	open (SSI, '< header.ssi');
	print <SSI>;
	close SSI;

or, as I think ModPerl allows you to keep persistant data:

	$/ = undef;

	my $header = &read_file('header.ssi');
	my $footer = &read_file('footer.ssi');
	my $blah   = &read_file('blah.ssi');

	sub read_file {
		open (TEMP, "< $ARGV[0]");
		my $temp = <TEMP>;
		close (TEMP);
		return $temp;
	} 

and then you can just print $header from Text::Template
