A reverse proxy is a type of server that sits between a client and a server, acting as an intermediary between the two. It accepts the requests from clients, forwards those requests to the appropriate server, and then returns the server’s response to the client. Reverse proxies are often used to improve the performance and security of web servers, and to allow multiple servers to appear as a single server to clients. For example, a reverse proxy can be used to distribute incoming requests to multiple servers, to cache static content to improve performance or to encrypt and decrypt traffic…
