You could use NPH (non-parsed headers), which lets you send multiple pages on one request. Check this silly page for an example (delays 10 seconds).

There were some tricks. The main one was I had to do use CGI qw(-oldstyle_urls) to make it work with Netscape 4.x. Basically, here is the way to do it:

use CGI qw(-oldstyle_urls); my $q = new CGI; # ... if ($q->param('last')) { last_page($q); } else { next_page($q); } sub next_page { # ... $url = $q->url('-query' => 1); $last = ($url =~ /\?/) ? '&last=1' : '?last=1'; # Here is the delay, 10 seconds print $q->header('-Refresh' => "10;URL=$url$last"), # print the rest of the 1st page here... } sub last_page { # ... print $q->header(), # etc... }
