I have rt set up on a server at home and am accessing it from the office as well.
The office connection is via WinGate.
The Display Queue action (http://myserver/rt/webrt.cgi) works fine from home
(inside my network), but externally through the proxy in the office, it always
brings up the login form.
Modifying the URL to http://myserver/rt/webrt.cgi? produces the correct action
