Default Document not displaying in IIS

I'd try investigating what exactly is failing before taking the sledgehammer approach of trying to modify the requested path in an iRule. I'm not sure why you'd get a failure if all you're doing currently is accepting an HTTP request and load balancing to an HTTP server.

 

 

You can use a browser plugin like HttpFox or LiveHttpHeaders for FF or Fiddler for IE to see what the exact request and response headers/bodies.
