Proxy Auth AND Destination Auth

[opticyclic]

I have set my proxy details in the settings.
If I make a request I get a response saying I am not authenticated. - This shows the proxy settings work.
If I go to the Auth tab and put in the user name and password for the destination I get an error saying I am not authenticated at the proxy!

Is there support for going through the proxy AND authenticating at the other end (with different username/passwords)?

The proxy never will hijack the authentication mechanism of the webapp. There could be some other issue.
