With CGI.pm, you can use the -expires switch to the header routine. Apparently, CGI::Util also has an expires routine that you can use to calculate the proper format. If you don't like digging around in the innards of CGI.pm, pull up HTTP::Date, which formats things according to the RFC. Something like this: 
use HTTP::Date qw(time2str);
my $now = time2str(time);
print "Expires: $now\nLast-modified: $now\n";
# add other headers here
