Forward proxy reverse proxy

Forward proxy is a client and originalServerTo get content from the original server, the client sends a request to the proxy and specifies the target (original server ), then the proxy transfers the request to the original server and returns the obtained content to the client. The client must make some special settings to use the forward proxy. The typical purpose of forward proxy is to provide a way to access the Internet for LAN clients in the firewall. Forward proxy can also use the buffer feature (provided by mod_cache) to reduce network usage. Use the proxyrequests command to activate the forward proxy. Because the forward proxy allows the client to access any website and hide the client itself, you must take security measures to ensure that only authorized clients provide services.

Reverse Proxy is the opposite. for a client, it is like an original server, and the client does not need to perform any special settings. The client sends a common request to the content in the name-space of the reverse proxy, and then the reverse proxy determines where (the original server) to transfer the request, and return the obtained content to the client, just as the content is originally its own. A typical purpose of reverse proxy is to provide the server behind the firewall to Internet users for access. The reverse proxy can also provide Load Balancing for multiple backend servers or buffer services for slow backend servers.
