Subject [jira] [Commented] (HTTPCLIENT-1347) gzip responses doubly cached
Date Tue, 14 Jan 2014 02:27:56 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1347?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13870310#comment-13870310
] 

Joe Campbell commented on HTTPCLIENT-1347:
------------------------------------------

Sorry about that - in the test client I put this back as you were saying the issue was around
gzip responses:

httpGet.addHeader("Accept-Encoding", "gzip");

Hmm - in the disk caching case it would have to be smarter about the linking for the body
(as jon pointed out above) it is linking the resource, so it isn't using double the space
in memory (it is re-using the reference for the byte array). You are correct that the naive
storage case is a direct out to disk of the in memory representation which would likely cause
there to be an additional space usage.

> 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.
