hmm, i've tried it on NT4 SP6a, XP SP1a, i haven't tried it on win2k at all
yet.
maybe i should.

no, i did wonder about doing that, but it says that for each GET request, it
will get the wpad file which seems a bit OTT.

i'm not really sure what you mean by that.
the clients i am testing with don't even hit the webserver that is serving
the file, so it's more fundamental than that i reckon.

that's fine, i don't have any virtualhosts or anything on the webserver.

yes, it does.
