Parsing common types of IP proxy protocols

IP proxy protocol is the key link in network communication, it is located between the user equipment and the Internet, acting as the bridge of data exchange. When we use a proxy, we do not have direct access to the Internet, but instead route requests through the proxy server and then send them to the Web server. The proxy protocol specifies the rules for exchanging data between the device and the proxy server.


1. Socks5 proxy: Universal proxy server

As a general proxy server, Socks5 agent plays an important role in network communication. It uses the Socks protocol and is a special proxy with many advantages and flexibility. In a specific network environment, such as an enterprise network or a campus network, direct access to the Internet becomes difficult or even impossible due to firewalls, security policies, and other reasons. In this case, the Socks proxy can help users effectively overcome these restrictions and successfully access the required network resources.

Characteristics and application of Socks5

A notable feature of the Socks5 proxy is that it works on top of the transport layer, which means that it is able to transparently support various network-layer protocols, including TCP and UDP. This makes the Socks5 proxy suitable not only for regular Web requests, but also for applications that require the use of other protocols, such as real-time communication, P2P file sharing, etc. Therefore, in many cases, Socks5 agents are widely used to support a wide variety of networking applications.

What are the possible reasons for not being able to access public data when crawling

The Socks5 server is usually bound to port 1080, which is its default port. The user device makes network requests by connecting to the Socks5 server, which then acts as a proxy for the user device. This intermediate proxy process hides the user's real IP address, while also allowing the user to bypass some access restrictions, improving the flexibility and anonymity of network access.

2, HTTP proxy: common WWW connection request

HTTP proxies play a key role as the most common type of proxy we use on the Internet every day. It is mainly used in WWW connection requests, is a very common proxy, widely used in browsing web pages, crawling data and other network operations. The characteristics and usage scenarios of HTTP proxy make it an indispensable part of many network applications.

How the HTTP proxy works

The HTTP proxy sits between the user device and the target server and acts as a transit point for data transfer. When a user requests access to a web page in a browser, the request is first sent to an HTTP proxy server, which then forwards the request to the target website. After receiving the response from the target server, the proxy server returns the data to the user. In this process, the proxy server acts as a middleman, hiding the user's real IP address and communicating with the target server on behalf of the user.

Common port of the HTTP proxy

HTTP proxies are usually bound to some common ports to make it easier for users to access the proxy server through these ports. Common HTTP proxy ports include 80, 3128, and 8080. These ports are default in many proxy server configurations, making it easier for users to set up proxies.

3. HTTPS proxy: Secure hypertext transfer protocol

The HTTPS proxy, or Secure Hypertext Transfer Protocol, was developed by Netscape and built into their browsers. It is mainly used to compress and decompress data and return the results transmitted over the network. The HTTPS proxy ensures transmission security. The proxy server receives only encrypted HTTP packets and cannot send corresponding TCP/IP packets based on the connection header. Therefore, the connection status is the same.

In summary, IP proxy protocol plays a crucial role in network communication, and common proxy types include Socks5 proxy, HTTP proxy, and HTTPS proxy. These proxy types have different applications in different scenarios. Understanding their characteristics and uses can help you respond to network access requirements more effectively, protect data security, and improve access efficiency. Choosing a suitable proxy protocol can provide users with a better Internet experience while ensuring stability.
