Consider a scenario where a web application receives a large number of requests from clients. An Application Gateway can be used to distribute the incoming traffic across multiple servers to ensure that no single server is overwhelmed with requests. A forward proxy can be used to cache frequently accessed content, filter malicious traffic, and provide SSL encryption to improve the security, performance, and reliability of the web application.
