What is the primary function of a proxy server?

The primary function of a proxy server is to act as an intermediary between a user and the Internet. This means that when a user makes a request for a resource, such as a web page, the request is first directed to the proxy server instead of going directly to the target server. The proxy server then processes the request, retrieves the necessary data, and forwards it back to the user.

This intermediary role offers various benefits, including improving security by masking the user's IP address, caching data to speed up access to frequently requested resources, and allowing for content filtering and control. By using a proxy server, organizations can manage their network traffic more efficiently and provide a layer of anonymity for users accessing the Internet.

The other options involve functions that are not the primary role of a proxy server. While website hosting, data storage, and network traffic management can occur in broader contexts or through different technologies, they do not encapsulate the essential purpose of a proxy server.
