We currently use an SSG-140 firewall in front of our servers and I am interested in setting up a reverse web proxy. I know I can do that using policy based routing and directing the traffic to a proxy server like squid. What I haven't been able to find in my searching is if there is a way for the firewall to detect if the proxy server is offline and when it is direct the traffic directly to the origin web server. Does anyone know if there is a way to do this in ScreenOS? I'm using ScreenOS 6.3.0r12.0
