A full URL? That's news to me. I use the following code. Looking at the code here, I may be using an ancient idiom that has since been superceded, but I offer it for completeness' sake.

use CGI qw/Link/;
my $q = new CGI;
print $q->header(),
  $q->start_html({
    -title => 'title of my page',
    -head  => Link({-rel=>'stylesheet', -type=>'text/css', -href=>'/fo
+o.css'}),
    });
[download]

I sorta like this, because it reminds me just what exactly I'm asking the script to emit.

update: I typed the above code in from memory, and in the original incarnation, I wrote -href=>'foo.css'. I checked some production scripts, and what I do In Real Life is -href=>'/foo.css'. This is not a relative reference (correct me if I am wrong), in that I am not using -href=>'../foo.css' -- I guess you could say it's absolute on the current server.

I was taking issue with the explicit http://... I don't believe that that is necessary, and it makes it a smidgin easier to transfer the script from one host to another.
