In TID 3988333, it says:

HTTPSAuthenticationSwitch=1 (0 to disable) (Default=0)
//To enable PROXY to try and redirect the browser to the domain name of the web server after SSL authentication. Using HTTPS Authentication, the original uri (complete path) is not available as a "GET" request and is not sent by the browser. By default the Proxy will force the user to re-enter the URI. Requires PXY026 or later.

In Craig's Proxy.cfg it is set to '0'.

Reading the above description and looking at the fact that the TID shows it set to '1', I would think the preferred setting would be '1', wouldn't it???
