Automatically changing proxy servers between sites

Posted on 2007-08-01

We have different physical sites for our company, and each use a different proxy server address obviously (Trend IWSS), my problem is that we have group policies set up for one site but when users go to site B they keep the same proxy which is flooding our link.
So i think i need to set up automatic configuration scripts in IE or block certian traffic on the routers.
Let me know your thoughts, thanks.

    I would suggest looking at using wpad entries to acheive this.

    Basically as I understand it when a browser starts up (if it is set to automatically detecte connection settings) it looks for a wpad entry on the network, this is supplied to the client by DNS/DHCP. The WPAD entry located then effectivly sets the proxy information.

    So if you configure DNS/DHCP on your 2 differant sites to supply a WPAD entry for the sites relevant proxy server then depending on which site your users log onto they will get the correct proxy address.

    I have not set this myself as I am still using a proxy.pac file where I work but I think it should be able to meet your needs. The other benifit is it allows you to set your broswers to automatically detect connection settings which is useful for laptop users working on foreign networks.

    More Info @

    As I have not set this up before I can not really give any more details on this.

    Hope it helps.
