Handling web request in a multiple SD application server set-up
I have two SD applications servers (SD1 and SD2). The inbuilt load balancing feature (multiple server option) has been enabled.
I am aware that in a multiple SD application server environment, we configure in the thick client, the SD application server to which all the request should be sent. If multiple server option is enabled then if this SD application server dies then the request will be routed to the next SD application server mentioned in the srv.dat file.
I need to know how exactly this same thing is obtained in case of web request? I want to have such a set-up that when the primary SD application servers (SD1) is down then the web request should routed to the secondary SD application server (SD2). How can we obtain this?
