This can be done without placing code or tags onto pages. Reverse proxies are often used to perform multivariate and A/B testing.Reverse proxies can compress content to reduce loading times.They can be used to distribute incoming requests to several servers, where each server will typically serve its own application area (aka, Global Server Load Balancing – GSLB).This is known as web acceleration or load balancing solution. Reverse proxies can cache static, as well as dynamic content to reduce the load on the origin servers.Removing malware could be difficult if a reverse proxy is not used.
Reverse proxies often use application firewalls to protect against web-based attacks, including distributed denial-of-service attacks (DDoS attacks) and Denial-of-service attacks (DoS).Web servers may use reverse proxies to perform SSL encryption, often by using SSL acceleration hardware.Thus, the servers that effectively store the data are not publicly accessible. Reverse proxies are used to hide origin servers.Implementing reverse proxies for handling web requests makes sense in certain situations that are listed below. The target server forwards the response to the proxy, the proxy server, in turn, reads the request and then returns it to the client.The request is sent to the target server.The configuration of the proxy rules determines which outbound URL the request should be sent to. The path is generally used as the primary data for routing. This is done by using any part of the URL to route the request. The reverse proxy server determines where the request needs to be sent to by analyzing the URL.The hostname is resolved to the reverse proxy server’s address and the proxy, therefore, receives the request. The client web application (e.g., a web browser) makes requests to public URLs.
