Subject [jira] [Commented] (HTTPCLIENT-1347) gzip responses doubly cached
Date Mon, 13 Jan 2014 21:27:50 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1347?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13870007#comment-13870007
] 

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

If you look at the implementation of a BasicHttpCache - Your entry gets a 'storeInCache' called...
in this case the entry "hasVariants" which then calls storeVariantEntry();

This method then takes the entry and stores it AS a variant and produces a callback which
would update the 'root' entry.  In this case, your method just stores the record that had
just been stored as the variant version into the root version (non-variant). 

		@Override
		public void updateEntry(String arg0, HttpCacheUpdateCallback arg1)
				throws IOException, HttpCacheUpdateException {

			System.out.println("updating entry: " + arg0);
			HttpCacheEntry entry = getEntry(arg0);
			----> putEntry(arg0, arg1.update(entry));
		}

> 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.
