    Prevent the browser to read cached Flash object

    Conti
      I have a slideshow Flash object which pics filename are supplied by an .XML
      file created dinamically every time the page loads.

      Unfortunately the .SWF is always being read from cache even though the .XML is changed
      correctly. The Flash movie always shows the pictures loaded at start of the application.

      I am able to refresh the Flash movie if:
      - I restart the application;
      - I set the browser setting to check for newer version of stored pages to "every time";
      - after 5/10 minutes have elapsed from the last reloading (couldn't find a real pattern here);

      To prevent caching I have tried the following:
      - Added a random number at the and of the URL that calls the page (...&r=#rundomNumber()#)
      - Added <META HTTP-EQUIV="Expires" CONTENT="Mon, 04 Dec 1999 21:29:02 GMT">
      - Added <META HTTP-EQUIV="Pragma" CONTENT="no-cache">
      - Added <META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">
      in various combinations.

      - Used <cfheader name="Expires" value="#GetHttpTimeString(Now())#">
      - Modified the param name="movie" to
      <param name="movie" value="Gallery.swf?id=#randomNumber()#" />
      or to
      <param name="movie" value="Gallery.swf?id=#randomNumber()#&xmlPath=gallery.xml&id=#randomNumber()#" />

      also

      Opening the Gallery.fla with Flash 2004 in the Component Inspector, parameter xml Path = gallery.xml changed to "gallery.xml?id=1"
      or
      "gallery.xm?Math.round(Math.random() * 99999

      all this to prevent the browser to read from cache and download a fresh copy from the server, but to no avail.

      Is there something else to be tried?

      Thank you for helping.
