One of the objectives of a CDN involves using a cookie-less domain to cut down
on the amount of data that needs to be transferred to the server to make a
request. I'm in a situation where I cannot use a cookie-less subdomain because
of a need to use ".foo.com" for cookies so that states persist across a
non-fixed set of subdomains on the host. For this reason I have a number of
subresources that transmit cookie data needlessly on any given page.

It would seem useful to allow a "rel" attribute on script/link/img tags that
tells the browser to not send cookies with that subrequest. This would make it
possible and very easy for developers to cut down on the amount of cookie data
being sent, especially in situations when they lack the authority or have a
specific obstacle to creating a cookie-less CDN to serve the resources over.
