Response caching policies define how long API Center stores API responses in the cache. You can reduce redundant backend load by creating response caching policies for operations.
When response caching is enabled for an operation, API Center saves responses to invocations of the operation in the cache repository. When API consumers access the operation, API Center attempts to use saved responses in order to reduce time and resources. If a matching response is found in the cache, API Center returns the response from the cache.
API Center deletes responses from the cache after the defined timeout. When you disable the response caching policy for an operation, API Center deletes responses from the cache for the operation.
You can configure a maximum timeout of 3,600 seconds.
The API References area of a response caching policy displays all the designed APIs that use the policy.
