The difference between HTTP proxy and SOCKS5 proxy

HTTP proxy: The ability to proxy client HTTP access, mainly proxy browser access to the Web page, its port is generally 80, 8080, 3128 and so on;
Socks Proxy: Socks Proxy Unlike other types of proxies, it simply passes the packet without caring about what 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 divided into SOCKS4 and SOCKS5, the difference is that the SOCKS4 agent only supports TCP protocol (Transmission Control Protocol), and the SOCKS5 agent supports both the TCP protocol and the UDP protocol (that is, the user Packet protocol), but 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.
