Subject [jira] [Commented] (HTTPCLIENT-1164) Compressed entities are not being cached properly
Date Sun, 04 Mar 2012 11:17:58 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1164?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13221852#comment-13221852
] 

Jon Moore commented on HTTPCLIENT-1164:
---------------------------------------

I think the issue is that you can't have length checks if the ContentEncodingHttpClient (however
it is implemented) is "under" the CachingHttpClient; rather you want the ContentEncodingHttpClient
to sit "on top of" the CachingHttpClient. So I think I'm going to go with the following:

1. Remove Content-Length at DecompressingEntity.
2. Implement a new decorator equivalent to ContentEncodingHttpClient.
3. Deprecate the existing ContentEncodingHttpClient.

> 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()
