Questions tagged [reverse-proxy]

A reverse proxy is a type of proxy server that fetches resources from a specific defined set of servers for a client. It is used in cases when there is an advantage to not exposing the web server with the content directly whether it be for security reasons or because of a lack of available public IP addresses.
