Different concepts
- HTTP proxy, which can proxy HTTP access of the client, mainly proxy browser to access web pages, its port is generally 80, 8080, 3128, etc.;
- SOCKS proxy, unlike other types of proxies, simply passes data packets without caring about the application protocol, which can be HTTP requests, so SOCKS proxy servers are much faster than other types of proxy servers. SOCKS proxies are divided into SOCKS4 and SOCKS5. SOCKS5 proxy supports both TCP and UDP (User Datagram Protocol), as well as various authentication mechanisms, server-side domain name resolution, etc.
Proxy speed varies
- The http proxy works at the application layer and only allows users to access external websites through the HTTP protocol;
- Socks5 proxy works at the session layer and does not require applications to follow a specific operating system platform. Socks5 proxy simply passes data packets without having to worry about the application protocol (such as FTP, HTTP, and NNTP requests). As can be seen from the above, Socks5 proxy is much faster than http proxy.
Different scope of application
- Socks includes https, and https includes http. Socks proxy has the widest application range.
- The https protocol only supports http/https, and the general IE proxy uses the http/https protocol. If it is an application layer protocol, http/https is generally not used. Some applications can only use socks proxy.
