I've once again refreshed my HTTP Cookie and Cache related Internet Drafts. The drafts have been discussed here a couple of times before, but to summarize:
draft-pettersen-dns-cookie-validate-04.txt (archive)
This Draft describes Opera's current heuristical approach to avoid sending cookies to registry-like domains like co.uk (The "Cookie Monster Bug"). First discussed here.
draft-pettersen-subtld-structure-04.txt (archive)
This Draft describes an improved approach to handling the "Cookie Monster Bug", using an online black list of registry-like domains. Also first discussed here.
The Mozilla team's work on "Effective TLDs" is based on an early version of this suggestion. The result of this work is now available from PublicSuffix.org, and is AFAIK currently used for one or more features by Chrome Beta, FF3, and IE8 Beta.
To reduce the complexity of the specification, and to avoid excluding possible solutions, I have now removed the previous suggestions for how the repository should be generated, and just shortly mention some possibilies in the Appendixes.
draft-pettersen-cookie-v2-03.txt (archive)
This Draft describes the ideal solution to the "Cookie Monster Bug", that everybody starts using a new format for cookies that completely remove the problem. First discussed here.
draft-pettersen-cache-context-03.txt (archive)
This Draft describes a method for giving sites a method to tell the client that a group of webpages are related, which can be used to better organize logouts. First discussed here.
