body: <p>How can I get and set the current web page scroll position?</p>
  
  <p>I have a long form which needs to be refreshed based on user actions/input.  When this happens, the page resets to the very top, which is annoying to the users, because they have to scroll back down to the point they were at.</p>
  
  <p>If I could capture the current scroll position (in a hidden input) before the page reloads, I could then set it back after it reloads.</p>
