Subject [jira] [Commented] (HTTPCLIENT-1347) gzip responses doubly cached
Date Tue, 14 Jan 2014 01:29:55 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1347?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13870266#comment-13870266
] 

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

Update is doing a put in the BasicHttpCacheStorage case...

from the code:
HttpCacheEntry existingEntry = entries.get(url);
entries.put(url, callback.update(existingEntry));

If existingEntry is null then this is a raw put, if it is an item, then this is a put with
the updated item - a single "UPDATE" to the entry in the cache. Like I said, the documentation
doesn't make this... obvious.

> 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.
