What are the differences between HTTP/SOCKS5 protocols in overseas IP proxies?

With the rise of big data on the Internet, proxy IP has become an indispensable part for many users to complete tasks. The main function of proxy IP is to change IP and break through IP restrictions. Users who have used proxy IP know that proxy IP is divided into many types, including long-term, short-term, and proxies of different protocols, and transparent, general, and high-anonymous.

First, let's look at the difference between the two

The difference between SOCKS5 and HTTP proxy:

1. The proxy speed is different;

1) HTTP proxy works at the application layer and only allows users to access external websites through the HTTP protocol.

2) SOCKS5 proxy works at the session layer and does not require the application to follow a specific operating system platform. The SOCKS5 proxy simply passes data packets without having to worry about the application protocol (such as FTP, HTTP, and NNTP requests).

Therefore, SOCKS5 proxy is much faster than HTTP proxy.

2. Different ports

1) The default port of SOCKS5 proxy is 1080.

2) HTTP proxies generally use ports 80, 8080, 3128, 8081, 9080, etc. These are just the most commonly used HTTP proxies. In fact, HTTP proxies do not limit ports.

Three: Different concepts

1) SOCKS5 proxy: It is a proxy server that uses the SOCKS5 protocol and is a universal proxy server.

2) HTTP proxy: Use HTTP protocol proxy server, mainly proxy browser to access web pages.

Next, let's look at the advantages and disadvantages of each.

HTTP

Advantages: popular, flexible and highly applicable.

Each core component of the HTTP protocol, including the request method, URI, status code, reason phrase, header field, etc., is not "hard-coded", allowing developers to customize, expand or interpret them at will, giving browsers and servers the greatest degree of trust and freedom, which is in line with the Internet's spirit of "freedom and equality" – if any function is missing, just add a field or error code or something.

Disadvantages: Communication uses plain text (not encrypted), the content may be eavesdropped, the identity of the communicating parties is not verified, so there is a possibility of impersonation, and the integrity of the message cannot be proved, so it may have been tampered with.

2. Socks5

Advantages: Socks5 is a proxy protocol for client/server environment. It is an Internet transmission protocol, mainly used for the intermediate transmission between the client and the external network server. Socks5 proxy simply transmits data packets without paying attention to the application protocol (such as FTP, HTTP and NNTP requests). Therefore, Socks5 proxy is much faster than other application layer proxies.

Disadvantages: If we are on a corporate or campus network and need to access the Internet through a firewall or through a proxy server, we may need to use SOCKS5.
