title: Handling Refreshes After Form Submission
body: <p>What is the best way to disallow a form to resubmit on a refresh? <code>!IsPostBack</code> doesn't handle refreshes. I have tried using a bool variable that sets to true on initial submission, but it seems to be resetting every time I load the page. </p>
  
  <p>I've read a bit about cookies but I'm not sure how to setup these up to pass between pages. </p>
  
  <p>My setup is:</p>
  
  <ul>
  <li>Default.aspx (&amp; Default.aspx.cs)</li>
  <li>Results.aspx (&amp; Results.aspx.cs)</li>
  </ul>
  
  <p>Do I setup cookies in web.config like SessionState? Is there something better to use than cookies?</p>
