1. Different concepts
HTTP proxy: can proxy client machine HTTP access, mainly proxy browser to access the web page, its ports are generally 80, 8080, 3128, etc.
SOCKS proxy: Different from other types of proxy, a SOCKS proxy simply delivers data packets, regardless of the application protocol. It can be HTTP requests. Therefore, a SOCKS proxy server is much faster than other types of proxy servers.
SOCKS proxy is classified into SOCKS4 and SOCKS5. The difference is that THE SOCKS4 proxy supports only TCP (transmission control Protocol). The SOCKS5 proxy supports both TCP and UDP, and supports various authentication mechanisms and server domain name resolution.
2. Different proxy speeds
(1) HTTP proxy works at the application layer and only allows users to access external websites through HTTP.
(2) Socks5 proxies work at the session layer and do not require applications to follow a specific operating system platform. Socks5 proxies simply deliver packets regardless of the application protocol (such as FTP, HTTP and NNTP requests).
As a result, Socks5 proxies are much faster than HTTP proxies.
In the process of proxy, you can combine IP with operation. If you want to test the use of different types of proxies , you can try RoxLabs, free test including global residential proxy IP resources, unlimited bandwidth, high availability.
