Squid 2 - ?huh? why two ICP ports?

[Steven Sporen]

Could somone explain why the need for two ports which look like they do the 
same thing.

#  TAG: icp_port
#       The port number where Squid sends and receives ICP requests to
#       and from neighbor caches.  Default is 3130.  To disable use
#       "0".  May be overridden with -u on the command line.
#
#icp_port 3130

#  TAG: htcp_port
#       The port number where Squid sends and receives ICP requests to
#       and from neighbor caches.  Default is 4827.  To disable use
#       "0".
#
#htcp_port 4827
Cheers
  Steve
