Subject [jira] [Commented] (HTTPCLIENT-1347) gzip responses doubly cached
Date Tue, 14 Jan 2014 02:29:54 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1347?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13870312#comment-13870312
] 

Adam Patacchiola commented on HTTPCLIENT-1347:
----------------------------------------------

Going back to what you said about gzipped versus other encodings, if the reason for this is
that they are different content representations then why would the two entries point to the
same data? Presumably the "Root" url would point to the ungzipped data, and the "Variant"
url would point to the gzipped data. So something smells there as well.

> Compressed responses are cached twice. 
> Run the attached server (node.js 0.8.22) and client tests. Create an "assets" directory
under where you are running the server and add two files named 1 and 2 ( < 1000000 bytes)
. You will see that after the test is run the cache dump output displays 2 sets of entries
for each request, each containing the full content length of the file.
> Changing the implementation of HttpCacheStorage updateEntry to not update non existent
entries (as I believe the correct implementation should do) throws exceptions.
