Subject: Proxy configuration - security questions

I have some questions about security aspects of the proxy configuration
of the CERN WWW-server:

-I am able to associate an Protect template with certain URL's, for instance:

Protection PROTNAME {
GetMask ...
}

Protect http:* PROTNAME

The GetMask defines the hosts that the server will proxy for. However,
I want to be able to limit the *destination* hosts: for instance, I do
not want proxy operation when the *destination* is X, Y, or Z. Am I right
that the CERN server cannot be configured in this way?
If so, I consider this to be a major shortcoming.

-I suspect that the "UserId" directive is ignored in the Protection template
for proxied URL's. Eg

Protection PROTNAME {
GetMask ...
UserId xyz
}

Protect http:* PROTNAME

does not seem to work (ie the proxied operation is run as root, not as xyz.
Am I right in this.
