title: Confirm Form Resubmission Error
body: <p>Iam not able to understand how to handle this error even after reading a lot.</p>
  
  <p>I have a main.php - which has two dropdown lists. After selecting values from any of the drop-dwon list when I click on browsers back button I can get back to main.php.

  <p>But in my second page, which feature.php -- where I go after a submitting the value from one drop-down list. In this page I have another drop-down list, where when I select a value, I get re-directed to another page. Now here when I use browsers back button I get -- Confirm Form Resubmission Error.</p>
