HTTP, or Hypertext Transfer Protocol, is the most widely used communication protocol for information transmission on the Internet. Internet data exchange is based on this protocol. It allows Hypertext Markup Language documents to be transmitted from a web server to a client's browser. At this time, the browser no longer sends requests directly to the web server, but to the proxy server. The proxy server then sends requests to the web server and returns the results to the browser. Based on the HTTP protocol, there is also an HTTPS protocol, which adds the SSL security protocol to the HTTP protocol and is a secure version of the HTTP protocol.
1. HTTP, as the most widely used communication protocol, can be used to improve network access speed. Since proxy servers are equipped with relatively large server hard disk buffers, they can continuously store newly acquired data in their local memory. If there are overlapping requests, the data in the buffer can be directly returned, effectively improving browsing speed and efficiency.
2. Secondly, it can also act as a firewall. When users access external networks through the proxy server, only one IP address will be displayed, and the external network cannot directly exchange information with internal users.
SOCKS5 protocol plays an intermediary role between the front-end machine and the server machine using TCP/IP protocol communication, making the front-end machine in the intranet able to access the server in the Internet, increasing the security of communication. When sending the request to the real server, the SOCKS5 server will not make any changes to the request data packet, will not parse the internal structure of the data, and will only forward it faithfully. It is generally used to assist in communicating with websites that have firewalls and restrict ordinary client access.
1. The SOCKS proxy protocol can be used to capture web data. The SOCKS5 proxy can capture data from any UDP and TCP transmissions. With the help of the SOCKS5 proxy, it can be used to capture web data such as video streams.
2. SOCKS5 proxy can also ensure the security of remote connections. For some companies nowadays, many of them have the need for remote connections. SOCKS5 proxy adds another layer of security authentication on the basis of the original identity authentication, which can better ensure the security of remote connections.
3. SOCKS5 proxy can be used for traffic-intensive data transmission. SOCKS5 proxy is often used for traffic-intensive activities such as content streaming or P2P sharing, and is more suitable for transmitting large amounts of data.
