Subject [jira] [Updated] (HTTPCLIENT-1164) Compressed entities are not being cached properly
Date Thu, 15 Mar 2012 17:55:38 GMT

     [ https://issues.apache.org/jira/browse/HTTPCLIENT-1164?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jon Moore updated HTTPCLIENT-1164:
----------------------------------

      Component/s:     (was: Cache)
                   HttpClient
    Fix Version/s: 4.2 Beta2

This should clearly go into 4.2, at least. Oleg, what's your thought on backporting? Do we
have plans for a 4.1.4 release anytime soon (or sooner than 4.2 GA)? I think this is technically
not a bug, per se, because everything still works correctly HTTP-wise. I'll default to backporting
it next week unless folks have opinions it's not worth it.

> org.apache.http.impl.client.cache.CacheValidityPolicy.contentLengthHeaderMatchesActualLength()
returns false for entities decompressed by ContentEncodingHttpClient, because the length of
decompressed entity stored in cache will be different from the length specified in the response
header.
> Consequently, gzipped/deflated entities will never be satisfied from the cache.
> Proposed fix: introduce new field in HttpCacheEntry() - actualContentLength, and populate
it with the actual content length rigth before the cache entry is stored in the cache. Change
the org.apache.http.impl.client.cache.CacheValidityPolicy.contentLengthHeaderMatchesActualLength()
method to compare
> entry.getResource().length() with entry.getActualContentLength()
