 ## How Azure Application Gateway works

 Let's review the [Azure Application Gateway components](/azure/application-gateway/application-gateway-components).
 
 - **Front-end IP address**. Client requests are received through a front-end IP address. You can configure the Application Gateway to have a public IP address, a private IP address, or both. 
-- **Listeners**. A listener is a logical entity that checks for incoming connection requests. A listener accepts a request if the protocol, port, hostname, and IP address match the listeners configuration. You must have at least one listener.

 - **Request routing rules**. A request routing rule is a key component of an application gateway because it determines how to route traffic on the listener. The rule binds the listener, the backend server pool, and the backend HTTP settings. When a listener accepts a request, the request routing rule forwards the request to the backend or redirects it elsewhere. If the request is forwarded to the backend, the request routing rule defines which backend server pool to forward it to.
 - **Backend pools**. A backend pool is a collection of web servers. Backend targets can include: a fixed set of virtual machines, a virtual machine scale-set, an app hosted by Azure App Services, or a collection of on-premises servers. The backend pool receives and processes requests. 
-- **Health probes**. Health probes determine which servers are available for load-balancing in a back-end pool. Servers are automatically added and removed from the backend pool based on their availability.

 One of the most important gateway configuration settings is the routing rules. The Azure Application Gateway has two primary methods of routing client requests: path-based  and multiple sites.

 ### Path-based routing
 
 [Path-based routing](/azure/application-gateway/url-route-overview) sends requests with different URL paths to different pools of back-end servers. For example, you could direct video requests to a back-end pool  optimized to handle video streaming. You could also direct image requests to a pool of servers that handles image retrieval.

-### Multiple site routing
+### Multiple site routings
 
 [Multiple site routing](/azure/application-gateway/multiple-site-overview) configures more than one web application on the same Application Gateway instance. In a multiple 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 a specific backend pool.

 ## Other routing capabilities
 Along with path-based routing and multiple site hosting, there are a few other capabilities when routing with Application Gateway.
