In IP proxies, three protocols are supported: HTTP/HTTPS/Socks5, which are interaction protocols between the client and the target server. The purpose is to complete data transmission between the client and the target server, and to perform target content retrieval operations on the client.

HTTP

HTTP, also known as Hypertext Transfer Protocol, is widely used on the Internet. It is a request/response model where the client sends a request to the server, and the server parses the request and responds to the client, then sends the response back to the client.

The HTTP protocol is stateless, and every request it sends is treated as a new request by the server, without caching relevant data for subsequent operations. Because the transmitted data is in plaintext format, users can see the returned parameter information after accessing the website, which poses a certain risk of data leakage.

HTTPS

HTTPS is based on HTTP and encrypts the transmission channel through SSL/TLS protocol to ensure the security of data during transmission.

It has good encryption strength for maintaining user privacy and data encryption, but due to the need for encryption processing, its transmission speed is lower than the HTTP transmission protocol. The HTTPS protocol is generally applied in fields with high security. IP proxies support the HTTPS protocol to protect user security information and provide secure and reliable network connections.

Socks5

The Socks5 protocol operates between the application layer and the transport layer, supporting TCP and UDP protocols, and can be used for various application proxies. For the HTTP and HTTPS discussed earlier, SockS5 can act as an intermediary between the two and the server, sending HTTP and HTTPS requests to the proxy server, which then forwards them to the target server, improving communication security.

The application fields of the three protocols overlap and differ, and over time, network transmission protocols are constantly improving and developing. Like HTTP changing from HTTP 1.0 to 2.0 and then to 3.0, it fills the gaps of HTTP and significantly improves transmission security. With the advancement of technology, transmission protocols will gradually become more complete and play an increasingly important role in the field of future network technology.
