Two questions:

1. How to set the address.family so requestHTTP will use a ipv4 address.
2. Where do I find the enumeration for the address.family using AFINET results in the following compiler error :source/app.d(8,70): Error: undefined identifier 'AFINET'.
3. How would I make it work using the web framework and/or the REST Interface.

The following code and execution output demonstrate the problem. In the first line a call to resolveHost with address family and use dns using the default an ipv6 address is returned [2607:f8b0:400d:c02:0:0:0:64]:0

The second line to resolveHost sets the address family set to 2 and use dns set to the default and ipv4 address is returned 98.124.44.234:0.

The call to requestHost results in the execution output detailed below. Essentially it Failed to connect to [2607:f8b0:400b:807:0:0:0:2004]:80 (Network is unreachable)

Any help is sincerely appreciated.

Thanks
John
