So, with the new 7.1 code it says that you are able to upload a proxy.pac file to the MWG to have clients reference it from that location. Where do you do that in the GUI? Also, does anyone have any favourite locations for this file? ie. NETLOGON share?
In the Configuration > File Server, enable File server for HTTP on port 4713 (by default)
Then in the Troubleshooting > Files, Upload the proxy.pac file. (or wpad.dat)
The URL to get the PAC will be:
wpad.dat is a special case that gets aliased to the root of the path.
