Question

Your company hosts two web applications, shop.contoso.com and portal.contoso.com, behind a single Azure Application Gateway v2. Both applications share the same public IP and port 443 but must route to different backend pools based on the requested domain name. Traffic for shop.contoso.com must go to the retail backend pool and traffic for portal.contoso.com must go to the internal-services backend pool. Which Application Gateway configuration achieves this?

Accepted Answer

Configure two multi-site listeners, each with its own host name, and associate each with a routing rule pointing to the appropriate backend pool.

Answer

Configure a single basic listener on port 443 and use path-based routing rules to separate the two applications.

Answer

Deploy two separate Application Gateways, one for each host name, sharing the same public IP address.

Answer

Configure a single multi-site listener and use a custom health probe to direct traffic to the correct backend pool.
