We are having some issues with our McAfee Web Gateway v188.8.131.52, when the client opens the web browser a pac file is loaded. Inside the pac file there are two proxies the Florida (FL proxy) and the fail over Minnesota (MN proxy). When the client makes a request and if the FL proxy is up the request happens through this proxy when the FL proxy is down the requests are sent to the fail over the MN proxy. The issue we are having is when the FL proxy is up but there is no internet connection behind it, it still accepts request which cannot go through since there is no internet connection. Is there a way that we can send those unresolved requests to the MN proxy until the connection returns to FL proxy.
