I know when using squid as an intercept proxy it can't do authentication as the 
clients don't know it's there, but do any of you out there know if you can use 
it with a parent proxy that requires authentication?

The specific scenario I am considering is Squid in DMZ with WCCPv2 used in 
conjunction with a Cisco ASA 5520 firewall and an external (Websense filtering) 
proxy that requires authentication, both NTLM and basic authentication is 
supported.

We are currently using auto-detect, but continually keep running into 
applications that don't recognize auto-detect, or sometimes don't even have the 
ability to read a configuration script.  I am trying to come up with a way to 
alleviate the user's issues, without losing our local cache.  And keeping the 
HR and Legal departments happy by continuing to filter websites with content 
that some could find offensive, as well as blocking unsafe (malware/spyware) 
websites.
