Comment # 2 on bug 9252 from Pascal Quantin

Hi Peter,

according to the WCCP v2 draft found here:
http://tools.ietf.org/id/draft-wilson-wrec-wccp-v2-01.txt, the Bucket encoding
is:

 Bucket 0-255

      Contents of the Redirection Hash Table. The content of each bucket is a
      web-cache index value in the range 0-31. If set the A flag indicates
      that alternative hashing should be used for this web-cache. The value
      0xFF indicates no web-cache has been assigned to the bucket.

       0 1 2 3 4 5 6 7
      +-+-+-+-+-+-+-+-+
      | Index       |A|
      +-+-+-+-+-+-+-+-+

So the current code seems valid. Could you pinpoint us the relevant spec that
indicates that the Alternate bit should be on MSB? Was it updated in a later
release?

Thanks,
Pascal.
