Nginx forward proxy and reverse proxy

Three characters

• Client
• Proxy Server
• Target server

Forward Proxy

The target server is visible to the client (whether or not the proxy server exists), but there may be a possibility that the client must go through the proxy server to access the target server (for example, Access www.google.com)

Reverse Proxy

The target server is not visible to clients, the client can only access the target server through a proxy server, and the client does not know what target servers are on the proxy server backend.

The above describes the Nginx forward proxy and reverse proxy, including the aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
