How Proxy Servers Work

Proxy servers accept and forward requests from clients (both internal and external networks) to various network services. This process ensures that they reach their intended servers. The client may be unaware that the interaction is taking place through a proxy server. When a proxy server accepts a client's request, the proxy can either immediately send the request to the requested resource, return the desired resource to the client from its cache, or block access to the requested resource. As a result, the proxy server is a critical component of the network architecture. Next, the website sends the data back to the proxy server, and the proxy server transmits the information on the web page to a browser. In this way, the proxy can act as a firewall and/or web filter that ensures that the web page displays only the required information.

You must establish the right settings in your browser to be able to access a network through a proxy. The proxy server's IP address will subsequently be used for all network connections. There is not a direct connection between your device and the website server. Sometimes, both the client and the intended machine do not realize that they're working with an intermediary. The server takes the information and forwards it to the recipient. This establishes a communication link between two devices even if they're incompatible with one another.
