Facebook for Blackberry Issue with logging out

Question

I am having a problem logging out of facebook on my Blackberry Curve 8530.  Every time i click on log out it just says "Updating" and it just sits there.  I take the battery out to reset, and when the phone comes back on, i'm STILL logged in. I shouldn't have to take the battery out. If I click logout, it should just logout. It's been this way for about a month now.  So what can I do about this annoyance?????

Hi , your problem is arising when user presses the back button of the browser , web browser shows the page from its cache. If you want that
on pressing the back button users should not view the previous pages you must stop web browser from caching the page to its local memory.
It can be done by adding the following code in the jsp:root tag of jsf (.jspx) page.
  <jsp:scriptlet>
  // Set to expire far in the past.
      response.setDateHeader("Expires", 0);
  // Set standard HTTP/1.1 no-cache headers.
     response.setHeader("Cache-Control", "no-store, no-cache, must-revalidate");
  // Set IE extended HTTP/1.1 no-cache headers (use addHeader).
     response.addHeader("Cache-Control", "post-check=0, pre-check=0");
  // Set standard HTTP/1.0 no-cache header.
     response.setHeader("Pragma", "no-cache");
</jsp:scriptlet>Now when ever page is loaded the web browser will never cache the local copy of web pages and hence users will not be allowed to view previous pages when clicking back button
on browser .
Hope this helps.
