title: Identifying HTTP_REFERER screen resolution of window outside div overlay
body: <p>I have a form which is overlayed over the visitors current page using jQuery when the user clicks on a div in the bottom right of a web page.  This overlay pulls up an iframe but I need to record the page the visitor clicked from to get to the overlay (essentially the HTTP_REFERER) along with the resolution of the window the user clicked from.</p>
  
  <p>As of now I am attempting to grab this information after the form has been passed, my concern is that the information I will be provided with will not not be correct and will instead give me the window size of the overlay and since it's a separate iframe won't be able to grab the HTTP_REFERER.  Are these assumptions correct?</p>
