title: Firefox Document Expired Issue over https
body: <p>I have a site that is running a combination of Perl and HTML. </p>
  
  <p>I've got a problem with the search function, where after I've searched for a keyword, and clicked the back button I get the Firefox "Document Expired" page. </p>
  
  <p>I've read several posts online and tried out a number of ways of fixing it, including putting in the pragma no-cache meta tags. </p>

  <p>I've been told by another developer that as the page is over https then there is nothing I can do to prevent this from happening as the browser is designed to prevent the information history for another user from being accessed. </p>
  
  <p>I'd just like to either confirm that this is correct and that there's nothing I can do about it, or if not whether anyone has any suggestions for workarounds that I might not have read about.  </p>
