I think Location should be included in that whitelist as well. It is not 
only used for 3xx redirection headers, but HTTP specifies that it can 
also be returned after a 201 Created request, to indicate the URL of the 
newly created resource:


Similarly, the Content-Location header should also be on the white-list.

Actually, I think all Content-* headers should be on the white-list, so 
including Content-MD5, Content-Length, Content-Encoding and Content-Range.
