What is the difference between HTTP and socks5 proxies?
HTTP proxy: can proxy client HTTP access, mainly proxy browser access web pages, its port is generally 80, 8080, 3128, etc. Socks proxy: Different from other types of proxy, the socks proxy simply transmits packets without caring about the application, even if the request is HTTP. Therefore, the SOCKS proxy server is much faster than other types of proxy servers. The SOCKS proxy is divided into SOCKS4 and SOCKS5. The difference between the SOCKS4 proxy and SOCKS5 is that the SOckS4 proxy supports only TCP (Transmission Control protocol), while the SockS5 proxy supports both TCP and UDP (User packet protocol), various authentication mechanisms, and server domain name resolution. SOCKS5 can be achieved by SOCK4, but socks4 may not be achieved by SOCKS5. For example, our common chat tool QQ requires SOCKS5 when using proxy, because it needs to use UDP protocol to transmit data.
