The localhost name is just a name. It follows the normal process to resolve to an address. So it only works if localhost is in the DNS cache (ie, you recently connected to it while online), because name resolution of non-cached names doesn't occur in offline mode. The patch itself only enables connection to loopback interfaces. It doesn't modify the DNS resolver to try to resolve unknown names in offline mode. The browser doesn't have any say over the resolution process once it asks for a record. That is, we can't restrict a lookup to only the hosts file (where localhost and other locally defined names are configured). An attempted lookup that doesn't resolve in the hosts file would try to hit the network. If that's deemed acceptable, then a subsequent patch could simply filter resolution requests in offline mode. That is, only pass them on if they are loopback. But it would mean that we would cause network traffic in "offline" mode. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/367531 Title: firefox should be smarter about offline access To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/367531/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
