Yes, your right. I need the myIpAddress(), however like you said it doesn't always works as desired. I also read somewhere that not all browsers support that particular function. Right now that's what im using (in theory I really don't care what proxy they use as they can authenticate to either, but it makes logical and geographical sense to distinguish between the two), but your idea seems pretty cool. What exactly do you do though? What kind of script do you point them to, is it the .pac java script? (anyway we can see a sample?). Im assuming you do it in the "Automatic Configuration Script" field in Internet Explorer, or do you still use the WPAD.dat file?

In my environment, I've solved this by having a single proxy script and setting all browsers to use the same URL, but the server where the file is hosted actually generates the contents on the fly. This way the script can be customized by the server in ways not supported in the client, including providing a different default proxy server/port to different clients. The other reason I do this is to eliminate 99.9% of the DNS lookups by the client -- in theory, we could disable Internet resolution by internal workstations (we've done this once or twice,mostly by accident) and so long as the proxy server was able to resolve, browsers would never notice. > For the life of me, I cannot get this to work.

Where you say: if (isInNet(host,"192.168.0.0","255.255.0.0")) I think you meant: if (isInNet(myIpAddress() ,"192.168.0.0","255.255.0.0")) While myIpAddress() is documented in the original Netscape specification, it doesn't have provisions for hosts with multiple interfaces. In the past I've seen false negatives, where the above test returns false when it really should have been true. That's one reason we instead have the web server hosting the script look at REMOTE_ADDR instead. Kevin -- http://wiki.squid-cache.org/Technology/WPAD ^Watch this space^
