title: How do you force Firefox to not cache or re-download a Silverlight XAP file?
body: <p>When working with Silverlight, I've noticed that Firefox will cache the XAP file, so if I do an update, a user may be stuck using an outdated version.  Is there a way to force the browser to either re-download the XAP file every time, or maybe only force it to after an update has been published?  Or is there a setting in the Silverlight config that stops the browser from caching the XAP file altogether?</p>
  
  <p>Thanks,
