This article introduces the knowledge of "how many types of proxy server". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. HTTP proxy: you can proxy the HTTP access of the client.

When we browse the web and download the data, we use the http agent. Its ports are generally 80, 8080, 3128, and so on.

2. HTTPS proxy: the HTTP protocol is not encrypted during transmission.

If you are transferring private files, there is a risk of insecurity. To keep it safe, HTTPS appeared. In fact, HTTPS protocol is a network protocol established by SSL+HTTP protocol, which can encrypt the transmission process, which is more secure than HTTP protocol to transfer files. The ports used by HTTP and HTTPS are different. HTTP is 80 and HTTPS is 443. Of course, the connection method is also completely different. HTTPS and SSL support certified HTTPS and SSL, and the user can determine who the sender is if needed.

3. SOCKS proxy: SOCKS proxy server is a public proxy server using SOCKS protocol.

(1) SOCKS agents are different from other types of agents. SOCKS does not require applications to follow a specific operating system platform. The SOCKS agent simply transmits data packets without worrying about what kind of application protocol it is. So SOCKS proxy servers are much faster than other types of proxy servers.

(2) SOCKS agent is divided into SOCKS4 and SOCKS5. The difference between the two is that the SOCKS4 agent only supports the TCP protocol (transmission control protocol), while the SOCKS5 agent supports not only the TCP protocol and the UDP protocol (that is, the user packet protocol), but also various authentication mechanisms and server domain name analysis. The SOCKS5 that SOCKS5 can do is possible, but the SOCKS5 that SOCKS5 can do cannot.

This is the end of the content of "how many types of proxy servers are there". Thank you for reading. If you want to know more about the industry, you can follow the website, the editor will output more high-quality practical articles for you!
