We currently use WPAD and it works fine, but our network department wants to change to use a PAC file on a BlueCoat (BC) using an autoconfig script. We need PC's in one region to use one BC and PC's in another region to use another. They asked me to create a DNS file that will change the IP of the hostname depending on the region. I do not know if this is possible. If it is, that would be cool.
So then he asked about putting the BC's behind an F5 which we only have at one location. Seems this would not be too effective since we do not have an F5 Cluster across the WAN. But we could go this route if we wanted to change.
Do you have any ideas for me? They are being persistent, we are happy with WPAD so would like to hear your ideas of the Pros and Cons of WPAD through IIS rather than PAC file through autoconfig script. ..and any way to do this better. Cluster the Bluecoats across the WAN possibly?
We have IE, Chrome and Firefox.
