Avoid form fields resetting when going back after following a link

I'd like to make sure that after editing and then navigating away from a form (pressing Back or clicking a link) and returning (using the Back or Forward button), the form data is not reset. I have verified that this works on another web site. What do I need to check?

Before answering, please note that I'm not submitting and then going back. Simply following links and then returning.

Most browsers cache form input values. So when user refreshes page, the inputs have same values.

You should check your code-behind for browser cache manipulations like:

<?
  Header('Cache-Control: no-cache');
  Header('Pragma: no-cache');
  ?>

and also your plain HTML-templates for:

<meta http-equiv="Expires" content="Tue, 01 Jan 2000 12:12:12 GMT">

or 

<meta http-equiv="Pragma" content="no-cache">
