title: IIS as reverse proxy
body: <p>I'm looking into to having IIS doing authentication in an application being executed on a J2EE server (JBoss). Is there any ways to have IIS work as reverse proxy and propagating the username and/or roles of the user the proxied application (JBoss). And also what IIS version would I need, if it's possible?
  I have license for IIS, so I'd like to do it in IIS, but otherwise I'd prefer open source.</p>
  
  <p>Thanks!</p>
