By default Squid complains if it finds an underscore in a URL
hostname.  It returns an "Invalid URL" error message and explains
that underscores are not allowed in hostnames.  Of course you can
make Squid accept underscores if you prefer.

We felt this was better than returning a "the domain name does not
exist" error message.  It sucks for the user when a name can be
resolved by one machine or by one application, but not by another.


Even on FreeBSD you get different answers from different apps:

        chef-wessels ~ 8> host super_bikes.tripod.com
        super_bikes.tripod.com has address 209.202.240.100
        chef-wessels ~ 9> ping super_bikes.tripod.com
        ping: cannot resolve super_bikes.tripod.com: Unknown server error
