title: Proxy servlet and iframe to run site from another domain
body: <p>For quite a long time I use proxy servlet, and from my experience in order for javascript to properly work, the proxy servlet has to be configured to run in the ROOT context. However, a site <a href="http://www.filestube.com/" rel="nofollow">http://www.filestube.com/</a> from what I investigated, its running a site from another domain on a iframe. </p>
  
  <p>I am wondering what kind of approach is this?  </p>
