In the Internet age, we are all familiar with terms such as HTTP proxy and HTTP protocol, but HTTP proxy has classification, which I'm afraid some friends don't know. Here is a brief introduction to you. Please see the following.
1. Rfc7230 - http / 1.1: General proxy described in Message Syntax and routing (the first part of HTTP / 1.1 protocol revision). These institutions act as intermediaries, and the client connected to them is the server; The server connected to is the customer. This mechanism is responsible for passing HTTP messages back and forth between the two ends.
2. Tunnelling TCP based protocol through web proxy servers. The system communicates through the body of HTTP protocol and implements any application layer protocol proxy based on TCP. This proxy uses the conect method of HTTP to establish a connection, but conect does not originally belong to rfc2616-htp / 1.1. The description of conect and tunnel proxy was not released until the 2014 http / 1.1 revision. In fact, this kind of proxy has been widely implemented, and many services also need HTTP proxy resources. Roxlabs provides proxy servers with different protocols, which can be extracted according to needs.
