What is the difference between socks5 proxy and http proxy?

Based on the difference protocols used by web servers, SOCKS5 and HTTP proxies are the two main types of protocols that proxies run. As we all know, proxy IP addresses can replace our local IP addresses, helping us bypass the IP blocking of some websites, while also protecting our local IP. Each type of proxy is designed for users to access different types of servers. It can play a good role in some demand scenarios. Today, Kookeey Proxy IP will discuss the differences between Http proxies and SockS5 proxies, which are most commonly used in IP proxies.

1. What is the difference between socks5 proxy and http proxy?

Socks5 proxy and HTTP proxy are two common types of proxy servers. The main differences between them are as follows:

1. Protocol: Socks5 proxy is a proxy server based on Socks protocol, while HTTP proxy is a proxy server based on HTTP protocol. In TCP, Socks5 proxy provides more protocol support, and HTTP proxy is mainly used for HTTP requests, such as UDP and ICMP.

2. Request processing: Socks5 proxy will not modify the data packet when sharing the request, it will directly forward the data packet to the target server. In addition, HTTP proxy will analyze the HTTP request header when sharing the request, and can modify the request content, such as adding some HTTP header information.

3. Access permissions: Socks5 proxies usually do not have strict access permissions, and can browse any target server and port. And HTTP proxies usually have access control lists that limit the target servers and ports that can be browsed.

4. Connection establishment: Socks5 proxy only needs one handshake phase to establish a connection, which is relatively fast. In contrast, HTTP proxy needs to perform TCP three-way handshake and HTTP request and response interaction when establishing a connection, which is relatively slow.

In summary, Socks5 proxy is more suitable for scenarios that require direct data transmission, such as file transfer and real-time communication. HTTP proxy is more suitable for scenarios that require modification of requests and responses, such as web browsing and HTTP API calls.

2. Do socks proxy and https proxy have the same scope of application?

1.socks includes https, https includes http, socks proxy has the widest application range;

2. The https protocol only supports http/https, and the http/https protocol is used for ordinary IE proxy. If it is an application layer protocol, http/https is generally not required, and some applications can only use socks proxy.

In short, the application scope of socks proxy and https proxy is different.
