Interesting. I just ran into this problem with content in one
directory that needed to be handled differently from the rest of the
content on the web server. I thought that I could handle this with a
shExpMatch(url, "string") function in the proxy.pac file.

Unfortunately, this doesn't work consistently as you run up against
Windows' default web proxy cacheing behaviour that does not allow
exceptions for a given web server or host. If the URL of the first
access to a given host results in a DIRECT being returned, IE will
use DIRECT for all content on the given host. If a PROXY is
returned, IE will use the proxy for all content on the specific host.

The last problem can be resolved but requires a Windows Registry
change to define "enableProxyResultsCache" and set its value to 0 to
disable the caching. I recommend that you search Microsoft's
Knowledge Base for the above string. I don't remember the exact
syntax and the article that I found had it wrong. :(
