IE10 and proxy settings RRS feed

  • Question

  • We are deploying IE10 to replace IE8. We found a problem on how IE10 manages Proxy settings which seems different from IE8.

    We have a PAC file that tells IE whether to use a proxy server or not. Up to IE8 our settings have been with "Automatically detect settings" off, "Use Automatic script configuration" on with the URL of the server delivering the PAC file, and then the manual proxy settings set as we need them in case the PAC file can't be delivered.

    As I said this works perfectly with all IEs up to IE8. Users when on the corporate network get one version of the PAC file and they can access the internet using our proxy. When at home and on the internet they get another version of the PAC file (which says go direct for all sites) and everything is fine.

    With IE10 things started to go wrong. After a lot of investigation I found that (at least on Windows 7) if I keep the manual proxy settings, the PAC file gets ignored. The PAC file works only if I take the manual proxy configuration off completely. Has the priority of the settings changed at all with IE10?

    With Windows 8 things are different again. Even without the manual proxy settings the PAC file doesn't get applied.

    I was going to experiment with WPAD to see if that makes any difference and it is going to take some time but I just wanted to see if anybody here has any clues of what is going on in IE10 with the proxy settings.
