Re: Squid 2.0 PATCH2 no-query peers and HUP.

The default is to send ICP queries. If you want HTCP you specify "htcp"
as an option and the port number (probably 4827 instead of 3130).
Maybe the default should be to have no "querying" method unless explicitly
specified, but this would mean changing the syntax of the config file quite
a bit I think.

This is most likely a sibling asking you for your cache digest, which
you haven't got built internally yet. It'll get built sooner or later
(look at the Event Queue in the cache manager to see when it's due next)
and then those messages will disappear.
