141654 - DNS: host lookup times out before demand-dialing completes

Status: VERIFIED DUPLICATE of bug 64857

(Core :: Networking, defect)

Description

[Jim Bray]

Using current mozilla or galeon, I reliably get a
'<host> could not be found...' error if the ppp link is
down and needs to demand-dial, as the demand-dial connection
seems to take about 5 seconds longer than mozilla/gecko wants
to wait.

 I've tried fixing this with the following prefs:

user_pref("network.http.connect.timeout", 999);
user_pref("network.http.request.max-start-delay", 999);
user_pref("network.http.request.timeout", 999);

with no luck. If there is a pref specifically for DNS query
timeout, please tell me about it, and if not, one would
be appreciated.

  I get the same behavior with old Netscape. I don't think it
is system-related, as if I do a host -s <big number>, host waits
long enough for the request to complete. Otherwise it times out also.

The underlying problem has to do with mozilla "fixating" on the pre-connection
DNS servers, and not recovering.

 This would be consistent with the behavior I'm seeing, as it seems to time
out just after the ppp connnection is made, at which point changes in 
IP addresses and routing take place.

Reporter: Do you still have the problem with Mozilla 1.1alpha?

  This behavior seems to have gone away at 1.0-pre<something>, about a month
or so ago. I don't have a box on the net to test with, but figured this
had been fixed, perhaps accidentally so.

Thanks

Duping to 64857, because of bug 133359 and because this bug isn't reproducable
anymore.
