[bind10-dev] recursor cache requirements - input required

[Likun Zhang]

Hi all,

I have updated the document of recursor cache according the comments from
the bind10-dev list, the latest version is 8.

http://bind10.isc.org/wiki/RecursorCacheRequirements

There is one "Questions" section in the document, the only question is what
the Key should be for the items in message/rrset cache

Shane's opinion is that only the class IN should be supported on the
recursor cache, so the key for items in message/rrset cache will be
"Query_name + Query_type". What shane said in his email is: Personally I
really think we should just support class IN on the recursive side. CH is
useful for getting ID.SERVER and the like, but nothing useful in the caching
side, and the only other class is HS which MIT can send us a patch for. We
can't get those 16 bits back from the protocol, but we can get them back in
our implementation'' 

I will appreciate the comments on it from the reader.

Thanks

Likun
