A proxy is a network proxy technology that can establish a virtual connection between a client and a target network. By using a proxy, the client can access resources on other networks, but the client is accessing these resources through the proxy server. The proxy server intercepts the client’s request and sends the request to the target network. After receiving the response from the target network, the proxy server returns the result to the client.
The benefits of using proxy technology include improved access speed and security for the client. The proxy server can cache web pages that have been accessed, allowing for faster responses when the client accesses them again. It can also review and filter client requests to prevent access to unsafe or illegal content.
In servers, common proxy software such as squid, TinyProxy, socks5 can be set up to provide proxy services. Users can access the network through a proxy by setting the IP address and port number of the proxy server, for example, by setting the IP address and port number of the proxy server in the browser, network resources can be accessed through the proxy server.
A forward proxy refers to the client accessing other network resources through the proxy server, so that the server only sees the proxy server’s request, and does not know the existence of the client, thus the client can get anonymous effect.
Reverse proxy refers to the proxy server representing the client to make requests to the target server, and the target server sees the proxy server’s request, without knowing the existence of the client, thus the client can also get anonymous effect. Reverse proxy is often used in scenarios such as load balancing and caching.
