Who are you hiding?
Proxies are intermediaries. The main difference is who they are working for.
Are they protecting the User or the Server?
Reverse Proxy
The Reverse Proxy acts on behalf of the Server. It sits in front of the web servers. You think you are visiting the website directly, but you are actually talking to the proxy, which decides which backend server handles your request.
