title: Prevent Back button from showing POST confirmation alert
body: <p>I have an application that supplies long list of parameters to a web page, so I have to use POST instead of GET. The problem is that when page gets displayed and user clicks the Back button, Firefox shows up a warning: </p>
  
  <blockquote>
    <p>To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier.</p>
  </blockquote>
  
  <p>Since application is built in such way that going Back is a quite common operation, this is really annoying to end users.</p>
  
  <p>Basically, I would like to do it the way this page does:</p>
  
  <p><a href="http://www.pikanya.net/testcache/" rel="noreferrer"><a href="http://www.pikanya.net/testcache/" rel="noreferrer">http://www.pikanya.net/testcache/</a></a></p>
  
  <p>Enter something, submit, and click Back button. No warning, it just goes back.</p>
  
  <p>Googling I found out that this might be a bug in Firefox 3, but I'd like to somehow get this behavior even after they "fix" it. </p>
  
  <p>I guess it could be doable with some HTTP headers, but which exactly?</p>
