No. With a PAC file, the browser decides which proxy to use for what kind of access. It's basically a program. But if a specified proxy should be down, the client will still try and contact it. > What would happen if one employee is loggen into lets say to an > Ebanking site to check his/her own account from work, and while he/she > having an active session, one of the cache servers goes down.
