What is the function of a proxy server?

The function of a proxy server is to act as an intermediary for requests from clients seeking resources from other servers. When a client makes a request for a resource, such as a web page, the request is routed through the proxy server, which then communicates with the target server on behalf of the client. This allows the proxy to handle several tasks, including filtering content, providing anonymity, and caching responses to improve load times for frequently accessed resources.

Moreover, proxy servers enhance security by hiding the client's IP address and can implement policies that control internet usage, such as blocking specific websites. This intermediary role is central to how proxy servers operate, making them essential tools in network management and security architecture.
