-- TLS termination functionality to reduce the amount of CPU capacity consumed by encryption and decryption operations
-- Session affinity to ensure that the same back-end pool host always serves a client connection to a web application

 ## Load balancing in Application Gateway
 
-Application Gateway automatically load balances the requests sent to the servers in each back-end pool using a round-robin mechanism. Load-balancing works with the OSI Layer 7 routing implemented by Application Gateway routing, which means that it load balances requests based on the routing parameters (host names and paths) used by the Application Gateway rules. 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.

 ### Multiple-site routing
 
-Multiple-site routing configures more than one web application on the same Application Gateway instance. In a multi-site configuration, you register multiple DNS names (CNAMEs) for the IP address of the application gateway, specifying the name of each site. Application Gateway uses separate listeners to wait for requests for each site. Each listener passes the request to a different rule, which can route the requests to servers in a different back-end pool. For example, you could direct all requests for `http://contoso.com` to servers in one back-end pool, and requests for `http://fabrikam.com` to another back-end pool. The following diagram shows this configuration:

 ## WebSocket and HTTP/2 traffic
 
-Application Gateway provides native support for the WebSocket and HTTP/2 protocols. The WebSocket and HTTP/2 protocols enable full duplex communication between a server and a client over a long-running TCP connection. This type of communication is more interactive between the web server and the client, and can be bidirectional without the need for polling as required in HTTP-based implementations. These protocols have low overhead (unlike HTTP) and can reuse the same TCP connection for multiple request/responses resulting in a more efficient resource utilization. These protocols are designed to work over traditional HTTP ports of 80 and 443.

 - Azure Application Gateway routing allows traffic to be directed from an endpoint in Azure to a back-end pool made up of servers running in Adatum’s on-premises datacenter.
