Comment:

 (In [4150]) Emit more headers when hitting 304

 When hitting 304, ETag, Content-Location, Expires, Cache-control and
 Vary should all be sent to the client.

 See http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.5
 for some more details

 Thanks to Rog?\195?\169rio Schneider for the patch.

 Fixes #529
