RE: WCCPv2 support

Yes, those are the comments that I was talking about. The options listed
are the only things that I can think of at the moment that I would like to
be able to configure. The code and structures used should be able to
support, or be extended to support any WCCP2 option defined in the spec.
Any config option that is requested by anyone else should be able to be
incorporated into the code fairly easily.
