SOCKS is an Internet protocol that facilitates the routing of network packets between client-server applications via a proxy server. SOCKS performs at Layer 5 of the OSI model the Session Layer (an intermediate layer between the presentation layer and the transport layer).

SOCKS uses a handshake protocol to inform the proxy software about the connection that the client is trying to make and may be used for any form of TCP or UDP socket connection, whereas an HTTP proxy analyzes the HTTP headers sent through it in order to deduce the address of the server and therefore may only be used for HTTP traffic. The following examples demonstrate the difference between the SOCKS and HTTP proxy protocols
