This configuration seems to work correctly - but this a false conclusion. If you look deeper in log output/files, you will see that there is still a double slash inside. Fortunately the final request the browser is sending to the apache-httpd is "/clusterjsp/", so the cookie is considered and the session is not lost. But on backend servers you still get the double-slashed request, e.g.: "10.x.x.x" "17/Sep/2012:10:43:04 +0100" "GET //clusterjsp/ HTTP/1.1" 200 1590 So when you perform someting like javax.servlet.http.HttpServletRequest.getRequestURI() on an applicationserver, you still will see the "//clusterjsp/".

Maybe we can improve the URL canonicalisation, so that we are independent of the config? The rfc is on our side ;) http://www.ietf.org/rfc/rfc3986.txt -> 3.3.
