title: Make browser to load silverlight page/xap even when server is offline
body: <p>Is it possible to force browser to reload a Silverlight application - basically .aspx and .xap files - even if the server goes down? I.e. not accessible to the browser. Like setting caching forever. I tried different cache-control and expires headers but it doesn't seem to make a difference, it's still either 200 or 304 requests.</p>
  
  <p>In other words, I want browser to load .xap once and then never send requests for it again, always loading from cache - never means not even 304s.</p>
  
  <p>In even other words, is it possible to make browsers, once they got page and related content, to use them from cache and not contact server at all?</p>
