HTTP Proxy
Can proxy client HTTP access, mainly proxy browser access to the Web page, its port is generally 80, 8080, 3128 and so on;
Socks Agent
Unlike other types of proxies, the SOCKS proxy simply passes the packet without caring about the application protocol, which can be an HTTP request, so the SOCKS proxy server is much faster than other types of proxy servers.
Socks agents are also divided into SOCKS4 and SOCKS5
The difference is that the SOCKS4 agent only supports the TCP protocol (Transmission Control Protocol), while the SOCKS5 agent supports both the TCP protocol and the UDP protocol (that is, the user Packet Protocol), and also supports various authentication mechanisms, server-side domain name resolution, and so on.
SOCK4 can do SOCKS5 can be obtained, but SOCKS5 can do SOCK4 is not necessarily able to do, such as our commonly used chat tool QQ in the use of proxy when using the SOCKS5 agent, because it needs to use the UDP protocol to transfer data
