Status: VERIFIED DUPLICATE of bug 86917

(Core :: Networking, defect)

Description

[Gervase Markham [:gerv]]

[ This bug is one of the recommendations in the W3C's "Common User Agent 
Problems" document, URL above. One bug has been filed on each recommendation, 
for deciding whether we do it and, if not, whether we should. ]

3.5 If a host name has multiple DNS entries, try them all before concluding
that the Web site is down.

     Many Web sites have a single hostname like www.example.org resolve to
     multiple servers for the purpose of load balancing or mirroring. If
     one server is unreachable, others may still be up, so browsers should
     try to contact all the servers of a Web site before concluding that
     the Web site is down.

% nslookup www.example.org
Server:  ns2.mindspring.com

Name:    www.example.org
Address:  192.0.34.72
