Proxy Caching

Proxy caching is a process where a middleman server (the proxy) temporarily stores copies of web content like websites or files. When a user requests data, the proxy first checks if it has a recent copy. If it does, it delivers that directly, speeding up access and reducing bandwidth use. If not, it fetches the fresh version from the original source, stores it for future requests, and then sends it to the user. This improves browsing speed, decreases server load, and conserves network resources by avoiding repeated downloads of the same content.
