Fails to try next server when resolving domain name if primary server returns no recursion available

[Bruno Girin]

Binary package hint: wget

In a situation where DNS servers misbehave, wget fails to try the next server if the primary returns "recursion not available" on a particular domain name, even if the secondary DNS server is able to answer the query.

See the output of nslookup and wget in such a situation:

bruno@nuuk:~$ nslookup www.camino.uk.com
;; Got recursion not available from 217.13.128.17, trying next server
Server: 83.218.143.36
Address: 83.218.143.36#53

Non-authoritative answer:
www.camino.uk.com canonical name = camino.uk.com.
Name: camino.uk.com
Address: 67.222.99.135

bruno@nuuk:~$ wget www.camino.uk.com
--2010-07-08 14:36:57-- http://www.camino.uk.com/
Resolving www.camino.uk.com... failed: Name or service not known.
wget: unable to resolve host address `www.camino.uk.com'

Expected behaviour: if nslookup is able to resolve the domain name, I would expect that wget and any other HTTP client be able to do the same rather than exit with an error.
