Underscores in hostnames

Hello,

        Recently a customer complained because he could
not get to beardie_fun.listbot.com. The name has an
illegal '_' in it, and squid complains.

        I compiled url.c with ALLOW_HOSTNAME_UNDERSCORES. This is
squid 2.1.patch2. Squid doens't complain about the underscore anymore
, but the DNS lookup fails. If I do an nslookup on the machine, it
works. I put an entry in the /etc/hosts for beardie_fun.listbot.com,
and everything works fine.

        This is on Freebsd 2.2.8. I took a look at the
source for gethostbyname and I don't see it checking for
illegal characters.

        Has anyone else seen this?

        Thanks,
        Jon Fraser
