I'm not a caching expert, but adding yet another mechanism (in addition 
to HTTP caching and the HTML stuff) should be done with a lot of care.

Nits: *if* you want to add yet another manifest file, please consider 
respecting <http://tools.ietf.org/html/rfc5785>.

Also: I would try to remove hacks / special cases. If there's a need to 
declare resources that should be fetched without cookies, then we should 
have a generic mechanism for that, not something special-cased for a 
specific URI.

Best regards, Julian
