I saw a few presentation about Proxy HA setting but nobody was able to describe me the data flow in details. I had to take a tcpdump and make my own investigation.
Please tell me if I am right?
1/ a request from client PC to cluster IP running at the active director node, proxy port
2/ if the active director is under load, it will change destination IP to the IP of the scanning node, destination port is the same(proxy port), source IP isn't changed
3/ the passive director node make a request to external web server
4/ passive director node send a data directly from cluster IP to the client IP(do SNAT, because cluster IP is running on active director)
Thank you for confirmation
