Implementation notes:
- RFC 6265 has been worked on with draft changes describing how cookies are actually being handled in the real world, in the bis versions of the RFC. While these changes have not yet been finalized, browsers in general do adhere to the latest available bis version of this RFC. Specifically, the long-standing exceptions for cookie names and values have been formalized, e.g. having quoted values. Our behavior has changed in that we now once again accept Tab characters (0x09) which is the one excluded control character from the range that is otherwise forbidden. We also no longer apply these checks exclusively to those in http headers, and any way of setting cookies must now adhere to the valid range. Cookies that fail these range checks for valid characters will be ignored.
