A proxy connection is a network connection method in which the client does not establish a direct connection with the server, but connects through a proxy server. The proxy server acts as a middleman, receiving the client's request and forwarding it to the server, which then returns the server's response to the client. A proxy server can be used to hide the client's IP address, speed up network connections, bypass firewalls, and more.
Proxy connections can be divided into the following types:
-
HTTP proxy connection: The client sends an HTTP request to the HTTP proxy server, and the proxy server sends the request to the target server, and returns the target server's response to the client.
-
SOCKS proxy connection: the client sends a request to the SOCKS proxy server, the proxy server will forward the request to the target server, and return the response of the target server to the client. Unlike HTTP proxies, SOCKS proxies can support multiple protocols, such as HTTP, FTP, SFTP, etc.
-
SSL/TLS proxy connection: The client performs encrypted communication with the target server through the SSL/TLS proxy server. The SSL/TLS proxy server can encrypt the connection between the client and the target server to protect the communication content from eavesdropping or tampering.
Proxy connections can be used to protect client privacy, increase network connection speed, and bypass network restrictions. However, it should be noted that the proxy server may also become a source of security holes, so when using a proxy connection, it is necessary to choose a proxy server carefully and ensure the security of the proxy server.
python-socks is a Python library for connecting to networks using the SOCKS protocol. The SOCKS protocol is a network protocol that can establish a proxy connection between the client and the server, enabling the client to use the network connection on the proxy server. SOCKS protocol can be used to implement some special network connections, such as network connections through firewalls or NAT.
The python-socks library provides a SOCKS client that can be used to create SOCKS proxy connections. it
