Prevent browser F5 refresh

Few things are more annoying than needing to prevent your web site's visitors from refreshing a page resulting from a form "post".

This solution works with Internet Explorer. Simply place this code in the "head" section of your page.

<script language=javascript>
document.onkeydown = function(){

if(window.event && window.event.keyCode == 116)
  { // Capture and remap F5
  window.event.keyCode = 505;
  }

if(window.event && window.event.keyCode == 505)
  { // New action for F5
  return false;
  // Must return false or the browser will refresh anyway
  }
  }

</script>
