title: Remeber iFram SRC when refreshing parent page
body: <p>I have an intranet I am building, and am learning web languages as I go.</p>
  
  <p>I have a basic html/php page that contains an iFrame, which most of my content is loaded into.</p>
  
  <p>I also have a login box that is a popup modal within the main page.
  When you fill in this popup and hit login, it refreshes the main page, so that it knows you are logged in, and can display your name etc etc.</p>
  
  <p>However, this means that the iframe SRC also resets to its default.</p>
  
  <p>Is there a way to retain whatever the current SRC of the iframe is, when refreshing the parent page?</p>
