Definition - What does Caching Proxy mean?
Caching proxy is a type of Internet/network caching technique that enables a proxy server to save recent and frequent website/webpage requests and data requested by one or more client machines.
It is a means to accelerate webpage and website requests by saving an instance of frequently used content and resources locally on the proxy server.
Caching proxy can also be referred to as web proxy caching.
Techopedia explains Caching Proxy
Caching proxy primarily enables improving website access times, minimizing data download and lowering bandwidth usage. Caching proxy works when the proxy server analyzes and stores an instance or some proportion of data for the frequently used websites and/or Internet based resources.
When a client request is made for any webpage or resource that matches data stored locally in a proxy cache, the proxy server instantly retrieves and delivers the data. The resource being stored on a local proxy server is delivered much faster and uses less bandwidth it would require to download it from the destination server.
