It appears that setConnectTimeout works only for the connection to the
remote host, not for DNS lookups before the connection is made. You can
pre-attempt the DNS lookup using JNDI, and set the JNDI environment
property com.sun.jndi.dns.timeout.initial to a value in milliseconds.
Then use the normal URLConnection mechanism to set the timeout for the
communication with the remote host itself.
