ping is not bound by the requirement of only accepting FQDN names, so it
allows for searches according to your search path configured in
/etc/resolv.conf unless you give it a FQDN (the trailing dot forces FQDN
notation). Squid does not by standards requirements.

Which is why we have /etc/hosts to deal with the odd cases. /etc/hosts
isn't bound by the hierarchical restrictions set out by DNS, allowing
one to create whatever FQDN names one want (including new toplevel
names).

Hmm.. maybe built-in /etc/hosts is support isn't in 2.4.. let me check.
Nope. Sorry about that. For /etc/hosts support you need to get the
current development version from
http://www.squid-cache.org/Versions/v2/2.5/, or compile your squid with
--disable-inernal-dns and set up /etc/nsswitch.conf to use hosts before
dns.
