First tip: Socket.ERROR is a constant, so printing it doesn't  
help much (as you probably noticed). More helpful is the function 
lastSocketError(), which returns a string with some details.

                         writeln("Connection Error ", 
Socket.ERROR, " ", lastSocketError());

Which tells you:

Connection Error -1 Resource temporarily unavailable



The reason that is an error is because you turned off blocking.

         listener.blocking = false;


So, since the connection hasn't had a chance to get established 
and transfer data yet, instead of waiting for it to finish when 
you called receive, it returned the error telling you to try 
again later.

The simplest thing to do here is to comment out that blocking = 
false line, letting receive just wait until data is available. 
Another option is to use Socket.select to notify you when data is 
available, and only receive then.

After that, make sure the req literal is all on one line to avoid 
http 400 errors (not sure if that was a result of copy/paste or 
not, probably) and you should get a response.


Another note: casting a string literal to char[] is usually a bad 
idea, because you can't write to them anyway. Best to just leave 
them typed as string. It should all still work the same after 
doing that.



Finally, if you want a higher level library to do this, check out 
std.net.curl: http://dlang.org/phobos/std_net_curl.html
