I'm not thrilled with 'unless', though. I'm not sure it's any clearer to specify the "unless" case than the "when" case. I guess we could change "origin-when-cross-origin" to "url-unless-cross-origin", but I'm not sure how to distinguish between the "unless" behavior: "unless-downgrade" sends no referrer. "unless-cross-origin" sends origin information. For that reason, I'd prefer "none-when-downgrade" and "origin-when-cross-origin", as they specify the important differences more clearly. All that said, I think I now agree with you that "default" might be better. :) Another nit, just "origin" (rather than "origin-always") and > "unsafe-url" to align with "none".

It'll annoy publishers, of course, but I suppose that's a bit outside the scope of this directive. it does seem like something that the user should have > control over and a browser should be able to have a conservative > policy for. > I agree. The spec (and <meta referrer> before it) notes that user agents should feel more than free to limit referrer information in whatever way they feel appropriate, regardless of the defined referrer policy. -- Mike West <mkwst@google.com> Google+: https://mkw.st/+, Twitter: @mikewest, Cell: +49 162 10 255 91 Google Germany GmbH, Dienerstrasse 12, 80331 München, Germany Registergericht und -nummer: Hamburg, HRB 86891 Sitz der Gesellschaft: Hamburg Geschäftsführer: Graham Law, Christine Elizabeth Flores (Sorry; I'm legally required to add this exciting detail to emails.
