What is the main purpose of a proxy server?

• A. To directly access the internet
• B. To enhance network security only
• C. To act as an intermediary for client requests
• D. To store data locally on a device

Answer: (C)

The main purpose of a proxy server is to act as an intermediary for client requests. When clients request resources from the internet, the request first goes to the proxy server, which then forwards it to the intended destination. This method allows the proxy server to perform several important functions, such as caching data to improve load times, filtering content, and providing anonymity for users by masking their IP addresses. By acting as a mediator, proxy servers can also enforce security policies and improve performance for network traffic. While enhancing network security is one of the functions that a proxy can provide, this is not its sole purpose. Similarly, accessing the internet directly is contrary to what a proxy does, as it serves as a gateway. Storing data locally on a device is not a function associated with a proxy server; rather, this describes local storage mechanisms utilized by individual devices. Thus, the role of a proxy server is fundamentally as a facilitator between clients and resources, which is captured by its function as an intermediary for client requests.
