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.

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. *** This bug has been marked as a duplicate of 64857 ***
