Cache Proxy

Definitions

1. A proxy that stores reusable responses and serves future matching requests from cache instead of always forwarding them upstream. Cache proxies are common in CDNs, reverse proxies, and internal gateways where reducing origin load and response time matters.

   In plain English: A proxy server that caches responses so repeated requests can be served more quickly.

   Example: "Putting a cache proxy in front of the read-heavy API cut origin requests dramatically, but it required careful invalidation when product availability changed."
