My company has purchased two Smoothwall Guardian web filters. Setup has been pretty straight forward, and we have one replicating to another one for failover.
We use a PAC file via group policy for a proxy redirect thru the primary device. Right now the PAC file is imbedded on the primary device, but this is where the documentaion gets thin. MY understanding is that in order for failover to occur, some logic needs to be put in place within the PAC file to redirect traffic to the secondary if it should become unavailable.
So my questions are, what would the entries in the PAC file be to redirect to the secondary device if the primary was unavailable, and being that the current policy directs to the primary device via "http://address
of primary/proxy.pac", wouldn't the PAC file have to now be in an external location in order to function properly?
