问题
I have a code that is using WinHTTP on Windows 7.
The problem i'm experiencing is that the connction to specific hostname takes a long time when the user tries to use an IPv6 address (that is disabled).
I want to configure the connection (maybe WinHttpConnect parametrs) to try IPv4 first.
Is there a way to set the address binding order?

The answer is: You cannot do this.
See Specify which Network Card/Connection Winhttp Must Use
