2. Use "A" in a Switch Rule (other than the default rule)
3. Save and switch to Auto-Switch Mode.

Please provide any additional information below. Attach a screenshot if
possible.
Using http://www1.rz.rwth-aachen.de/pac/rwth-anon-proxy.pac in the same Proxy 
Profile as above works! I got this alternative URL here:

I noted an "XmlHttpRequest Exception 101" in RuleManager.downloadPacScript - 
could this be due to redirection?
