title: Post redirect get method does not prevent form resubmission on clicking back
body: <p>I have a login page that presents a login form. On submit, the page will send the data to itself for validation. If validation is successful, the user will be redirected to another page. I suppose this is the POST/REDIRECT/GET method discussed in <a href="https://stackoverflow.com/q/660329">this post</a>.</p>
  
  <p>The following is what I see the network tab on Chrome developer console when I perform a successful login:</p>
  
  <pre><code>Name     Method  Status
  login    POST    303 See Other
  profile  GET     200 OK
  </code></pre>
  
  <p>When I click the back button, instead of going back to the login form page, I don't quite understand why Google Chrome 28.0 still ask for a "Confirm Form Resubmission". Firefox doesn't seem to have this problem. What is the expected behaviour in this case?</p>
