Robert Newson resolved COUCHDB-2042.
------------------------------------
Resolution: Invalid
The DELETE method returns a header that instructs the user agent to discard the
cookie they've stored. In your examples, you have not done so (curl supports
options to read and write a cookie jar that you are not using).
Cookies have an embedded timestamp, signed by the server, after which they are
not considered valid. CouchDB does *not* have any knowledge of outstanding
sessions and, thus, cannot delete sessions.
If a browser is not clearing the cookie on sign out, that's a bug. This
demonstration with curl is not demonstrating the bug you think it is.
> Session not cleared after DELETE /_session (cookie auth)
