 * Hi,
 * Our wordpress theme loads some additional content from external sources, for 
   instance RSS feeds, data from web services, data from a vBulletin forum and so
   on. This additional content is displayed on the front page, together with the
   latest WordPress posts. We’ve had this feature for more than one year without
   any problems (WordPress versions 3.6 up to 4.0).
 * After upgrading to WordPress 4.1, some users started to complain that quite often
   the additional content on the front page is updated, but they still see the old
   content until they hit Ctrl+F5, bypassing the caches.
    We don’t do any magic 
   with the additional content. Some parts of it are buffered in the database, but
   usually the content is displayed without any special caching. As far as I know
   WordPress has some logic to decide when it should set the nocache HTTP header
   and of course this logic cannot know about the additional content that we load.
 * So my question is: Assuming I want to display dynamic external content on the
   WordPress start page, how can I make sure WordPress gets informed about changes
   in this content? I don’t want to disable caching completely.
 * Regards
    TiKu
