Proxies are divided into HTTP proxy, HTTPS proxy and socks proxy.
1. HTTP proxy. WWW is familiar with everyone on the Internet. Www connection request is HTTP protocol, so we use HTTP proxy when browsing web pages and downloading data (or using FTP protocol). It is usually bound to ports 80, 3128, 8080, etc.
2. HTTPS proxy. The Secure Hypertext Transfer Protocol (HTTPS) developed by Netscape is built into its browser to compress and decompress data and return network transmission results. In fact, HTTPS uses Netscape's full access layer (SSL) as a sublayer of the HTTP application layer. (HTTPS uses port 443 instead of port 80 to communicate with TCP / IP like http. SL uses 40 keywords as RC4 stream encryption algorithm, which is suitable for business information encryption. HTTPS and SL support X.509 digital authentication, and users can confirm who the sender is when necessary. SL uses 40 keywords as RC4 stream encryption algorithm.
3. Socks proxy. The proxy server using socks protocol is SOCKS server, which is a general proxy server. Socks is a circuit level bottom gateway developed by David Koblas in 1990. It has always been an open standard of network standards. Socks does not require applications to follow a specific operating system platform. Socks proxy is different from application proxy and HTTP proxy. Socks proxy is just a simple data For packet transmission, don't worry about the application protocol (such as FTP, HTP, NNTP request).
Therefore, socks proxy is much faster than other applications. It is usually bound to port 1080 of proxy server. If you need to access the Internet through firewall or proxy server, you can use socks. Generally speaking, users do not need to use dial-up Internet. Please note that the proxy server commonly used when browsing web pages is usually a special HTTP proxy, which is different from socks. Therefore, browsing web pages is not easy It means you can surf the Internet through socks. Ordinary firewall or proxy software supports socks.
The above are the categories of proxy servers. Roxlabs provides proxy servers with different protocols, including global IP resources.
