DNS based commConnectBegin() calls results in unconnected sockets.. #17

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
When using a very slow nameserver for testing, I've discovered that the current 
codebase creates 
the socket for the forwarded connection -before- doing the DNS lookup. This is 
bad for a variety of 
reasons, including:

* tying up unbound sockets for hosts which may not exist;
* making the transport layer decision (ie, IPv4!) before the DNS reply has been 
parsed;
* it seems ugly.

I'm not sure if this is the best way of doing this..
