Date Wed, 30 May 2012 08:23:23 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1487?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13285497#comment-13285497
] 

Robert Newson commented on COUCHDB-1487:
----------------------------------------

Probably missing a "Vary: Accept" response header in general here. Will confirm with spec.
