What is the correct way to negate the (default) resolver flag, address_configured?
On Windows, at least, specifying address_configured (which translates to AI_ADDRCONFIG) has a nasty side effect. If the 'external' network is down, the resolver can no longer resolve the "localhost" address. More here http://src.chromium.org/viewvc/chrome/trunk/src/net/base/host_resolver.cc?r1=16212&r2=16211
address_configured is the default flag for ip::basic_resolver_query so I need to specify a flag that turns it off. In the underlying addrinfo struct this would just mean specifying 0 as the flag but that isn't an option with ASIO as far as I can tell. How would I do this?
I ran into this problem, and came up with the following workaround: boost::asio::ip::tcp::resolver::query query( hostname, port, boost::asio::ip::tcp::resolver::query::all_matching ); HTH
