However, you can configure session stickiness if you need to ensure that all requests for a client in the same session are routed to the same server in a back-end pool.
 
 Load-balancing works with the OSI Layer 7 routing that Application Gateway routing implements, which means that it load balances requests based on the routing parameters (host names and paths) the Application Gateway rules use. In comparison, other load balancers, such as Azure Load Balancer, function at the OSI Layer 4 level, and distribute traffic based on the IP address of the target of a request.
