title: Make an iframe (or similar) load its content through a websocket proxy?
body: <p>I would like to display a existing sub-site in an iframe.</p>
  
  <p>The twist is that I would like the content to be served via a custom Websocket http proxy.  The server-side of the Websocket would handle retrieving the original sub-site content via http from the origin server.</p>
  
  <p>I assume that all iframe browser (and Ajax) resource loading calls would need to be intercepted and satisfied by some Javascript code, which would get the needed resources via a Websocket connection.</p>
  
  <p>Is this plain impossible?</p>
