Thank you.

Please port to 3.HEAD or 3.2 and submit to squid-dev mailing list for
checking. You will find the src/snmp_core.cc changes far easier in the
new version :) and the rest should apply easily.
The submission procedure for patches can be found here:
    http://wiki.squid-cache.org/MergeProcedure

It would be worthwhile answering these questions in your submission
email (ie the use-case/commit message for this change):

   How does this differ from "cacheHttpOutKb - cacheHttpInKb" ?
   Why should we include this in Squid?
