[jira] Created: (HTTPCLIENT-975) add support to caching module for
RFC 5861 (stale-on-error and stale-while-revalidate)
add support to caching module for RFC 5861 (stale-on-error and stale-while-revalidate)
--------------------------------------------------------------------------------------
Key: HTTPCLIENT-975
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-975
Project: HttpComponents HttpClient
Issue Type: New Feature
Components: Cache
Reporter: Jonathan Moore
These are Cache-Control extensions that allow an origin server to specify some additional behavior for stale cache entries. Stale-on-error configurations allow a cache to continue serving stale content for a certain period of time if a revalidation fails, and stale-while-revalidate similarly allows revalidation to occur asynchronously. Some reverse proxies such as Squid can be configured to understand these headers, which means that some origin servers are probably sending them, and that we can likewise take advantage of them.
