A proxy, also known as a Proxy Server, is a valuable network service that enables clients to connect indirectly with target servers through a proxy service. This service is useful in protecting the privacy and security of network terminals. The proxy server acts as an intermediary, whereby the client first establishes a connection with the proxy server and then, based on the proxy protocol used, requests to establish a connection to the target server or obtain specified resources from it. The proxy server can download and cache resources from the target server, and if the requested resources are in its cache, it can return them directly to the client. The fundamental function of the proxy server is to receive the client's request and forward it to the target server.

Proxies can help to hide our IP address, improve access speed, and bypass access restrictions. With many proxy service providers available in the market, it is crucial to compare and test several before choosing one. MaxProxy is one of the well-known overseas proxy service providers.
