1). HTTP proxy is a proxy server that processes requests through the HTTP protocol and is commonly bound to ports 80, 3128, 8080, etc. on the proxy server. 2). The HTTP proxy server also supports HTTPS (Hypertext Transfer Protocol Secure) by using port 443 and implementing X.509 digital authentication. 3). Socks proxy is a type of proxy server that connects requests using the SOCKS protocol. It is a general-purpose proxy server and is typically bound to port 1080 on the proxy server.

The Socks proxy, due to its use of the SOCKS protocol, offers faster speeds compared to other application layer proxies. It is commonly used on enterprise or campus networks to access the Internet through firewalls or proxy servers. Dial-up Internet users usually do not require the use of Socks proxy. It is important to note that the proxy server commonly used for web browsing is usually a dedicated HTTP proxy, which is different from SOCKS. Thus, just because you are able to browse the web does not mean you can access the Internet using Socks. Many commonly used firewalls and proxy software support the SOCKS protocol.
