What is one benefit of caching in a proxy server?

Caching in a proxy server is primarily beneficial because it improves user response time for frequently requested sites. When a user makes a request for a webpage or resource that has been previously accessed and stored in the cache, the proxy server can quickly deliver the cached content without needing to retrieve it from the original source over the internet. This significantly reduces latency and speeds up access to frequently visited pages, resulting in a better user experience.

The benefits of caching extend beyond just faster access times. By reducing the amount of data that needs to be transferred over the network, caching can also alleviate bandwidth usage, leading to an overall more efficient use of network resources. This is particularly advantageous in environments with multiple users accessing similar content, such as in corporate networks or educational institutions.
