244233 - connect failure on stale cached resolved ip

Status: RESOLVED EXPIRED

(Core :: Networking: HTTP, defect)

Description

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040207 Firefox/0.8

Google took one of its servers out of service.  The ip addr seemed to be cached
and foxfire didn't perform a fresh lookup before giving up on connecting saying
"google.com could not be found, please check the name and try again"

nslookup found an ip for www.google.com, ping proved it alive.

Reproducible: Always
Steps to Reproduce:
1.find a server that will be taken out of service
2.dns resolve that server
3.try to connect to the server once its been taken out

Actual Results:  
"google.com could not be found, please check the name and try again"


Expected Results:  
Perhaps if one can't find a route to a host one might try re-resolving.  Perhaps
it is google.com that is taking their servers out of service prior to the
expiration of their TTL.  Perhaps a good failsafe would be to try to initiate a
fresh dns lookup after connection failure with the dns server responsible for
the domain in question and if the results are different attempt to connect there.
