title: JQuery sliding div only once per Browser Session (or IP)
body: <p>I need an div (for advertisement) that slides down like here (when loading the page): <a href="http://www.webintenta.com/Files/JQueryCollapse.html" rel="nofollow noreferrer">http://www.webintenta.com/Files/JQueryCollapse.html</a></p>
  
  <p>Tricky part: When I click on the [x] the whole div should disappear. I want it to disappear for the Browser Session or better for the IP that accessed it. Saving it to a Cookie would also be a solution.</p>
  
  <p>How can I do that?
  Thanks</p>
