Re: [squid-users] proxy.pac

Yes, only when using WPAD.

Although some of the proxy.pa requests did make it to the webserver, the
majority of those requests required me to
actually sniff the machines manually to find them.

 I wonder if they resolved the issue in a relatively recent service pack
or something similiar.
I know for a fact, about a year ago, it was happening on a lot of machines
here.

Like I said, we stopped using WPAD just like they stopped working on the
RFC.

If I'm reading this right, you're saying that this problem only happens
when using Proxy Automatic Configuration (PAC) in combination with
the automatic discovery feature (WPAD) of MSIE?

Interesting. We support many thousands of Windows workstations,
all using proxy.pac but none using WPAD.

I do not see any requests for "proxy.pa" in the logs on the web server
hosting the PAC file. I do see a ton of errors for some really humorous
typos -- it's amazing how many different ways there are to creatively
spell "proxy" :)

(P.S. I do see a high number of requests for "proxy.pac?Type=WMT",
is anybody else seeing these?)
