>                 Key: HTTPCLIENT-1630
>                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1630
>             Project: HttpComponents HttpClient
>          Issue Type: Bug
>          Components: HttpCache
>    Affects Versions: 4.4 Final
>            Reporter: Philip Boutros
>              Labels: stuck, volunteers-wanted
>             Fix For: Stuck
>         Attachments: cachedir.png, code.txt, http-sometimes.txt, http.txt
> See the attached log of a GET with a 200 response followed by a GET to the same URL which
receives a 304 response and a CacheResponseStatus of VALIDATED. Using a HttpClient initialized
as in the other attachment, these two requests result in 2 identical files in the cache directory,
not one. 
> Additional info: This happens with multiple repeated requests that receive 304. Sometime
however the file is served from the cache with no additional copy. See new http-sometimes.txt
attachment for what that looks like.
> More info: Code work fine against various URLs that include Cache-Control, etc. in their
response, but has the same multiple copy behavior against any response that includes only
ETag and Last-Modified.
