SOCKS Protocol

---

The SOCKS protocol enables a client application, for example, a Web browser, to establish a connection to the server through a proxy, regardless of the Internet protocol being used. Instead of sending the data directly to the server, the client application "wraps" the data sequence to be sent in SOCKS protocol traffic and sends it to the proxy. The proxy unwraps the traffic and forwards it to the Web application that the client application wants to connect to. Once a connection between the client and the server has been established, the flow of traffic follows the usual protocol.
