Back button refresh page
<p>There are a few similar questions posted here but none that really addresses my needs.</p>

<p>I have a list of items on one page, lets call it masterlist.aspx.  If I click on one these list items another page appears, i.e. details.aspx?id=something.</p>

<p>The page that appears has a formview control in edit mode.  If the user wants to edit the data they hit an edit linkbutton and, the form is sent into edit mode, they then edit the data and click the save button, saving the data and putting the formview back in view mode.</p>

<p>The issue is if the user uses the browser back button to go back to the masterlist.aspx page the page is not updated, it's pulled out of the browser cache.</p>

<p>I have played around with the HTTP headers cache settings but can't get anything that works on all major browsers.  On some browsers I get web page expired warnings.  Another option is to somehow trigger a page refresh (or partial page refresh) when the page loads using client side code, but I haven't been able to figure out how to do this.</p>

<p>Is there any other approach or has anyone been successful with the two approaches above, or is there some way of avoiding the issue completely.</p>
