Unfortunately not all browsers respect the expires directive, you might try the following to add the no cache pragma to the headers when you output the page you want to expire:

tachyon

# if using CGI.pm to generate output try: print $query->header( -type => 'text/html', -expires => '-1d', -Pragma => 'no-cache', -Cache-control => 'no-cache'); # if directly outputing try: print <<END_OF_HEADER; Status: 200 OK Expires: now Pragma: no-cache Cache-control: no-cache Content-type: text/html END_OF_HEADER

This should generate a page expired message when you try to go back. </code>
