[squid-users] Certain header not authenticating

Hey,

I am running squid/squidGuard with NTLM authentication. Everything works
perfectly, except there is a site that some employees use for interactive
training. It seems when these employees go to this site they are continually
prompted for username/password with wpad.domainname.com as the realm.

After investigating, the useragent log is showing this:
192.168.12.102 - - [15/Feb/2006:15:30:49 -0500] "GET /wpad.dat HTTP/1.1" 200
251 "-" "NSPlayer/9.00.00.2980"

It seems that the NSPlayer header is somehow not retrieving the wpad file
correctly? If the users click cancel nothing happens - they can continue,
but it pops up when they click to go to the next page. This is a major
annoyance for some users, and has become a headache for me. I haven't
explicitly set anything in squid.conf to only allow certain headers, im not
even sure if you can. I have searched hell and high-water, but to no avail.

Does anyone have any ideas?

I really appreciate it.
