What protocols does the proxy IP software support? Are there any differences? Speaking of proxy IP, many people should be familiar with it. In fact, there are still some protocols when using IP proxy software, but you must know which protocols are supported. So after figuring out the protocols, the editor below will help you summarize the relevant knowledge. I hope it can help you.
What protocols does the IP proxy software support? 1. HTTP
Hypertext Transfer Protocol (HTTP) is the most widely used network protocol on the Internet. All WWW files must comply with this standard.
2. HTTPS
A more secure hypertext transfer protocol. That is, the SSL layer is added under HTTP. The security basis of HTTPS is SSL, so the encrypted details require SSL.
3. SOCKS4 and SOCKS5
SOCKS proxy is divided into SOCKS4 and SOCKS5
SOCKS5 is a proxy protocol that plays an intermediary role between the front-end machine and the server machine that communicate using the TCP/IP protocol, allowing the front-end machine in the intranet to access the server in the Internet or make communication more secure.
But the difference is that SOCKS4 proxy only supports TCP protocol (Transmission Control Protocol), while SOCKS5 proxy supports both TCP protocol and UDP protocol (User Datagram Protocol), as well as various authentication mechanisms, server-side domain name resolution, etc.
SOCKS5 can do what SOCK4 can do, but SOCKS5 can not necessarily do what SOCK4 can do. For example, our commonly used chat tool QQ requires the use of a SOCKS5 proxy when using a proxy because it needs to use the UDP protocol to transmit data.
