Use the Cache-control (for HTTP 1.1) and Pragma (for HTTP 1.0) headers to say the page should not be cached. You can also use the Expires header to say it expires immediately. 
print $cgi->header(-expires => 'now', 
  -Cache_control => 'no-cache', -Pragma => 'no-cache');

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
