---------------------------------------
Summary: CacheValidityPolicy does not correctly handle 304 Not
Modified freshness
Key: HTTPCLIENT-1579
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1579
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient
Affects Versions: 4.3.5, 4.3.4, 4.3.3, 4.3.6
Reporter: Nitin Kumar
When a cached response expires, http cache client correctly makes a new request
to the http server. When the response is still fresh at the server side, the
server responds with HTTP/1.1 304 Not Modified and sends in a new Expires:
header.
On subsequent request, when the cache entry should be still valid as per the
time stamp received in the Expires header from the last call,
CacheValidityPolicy tries to validate the cache entry in the isResponseFresh()
method and incorrectly marks the the entry as stale.
The result is that http cache client keeps making new requests to the http
server.
