Using std.net.curl to stream data

[Trollgeir via Digitalmars-d-learn]

I'm having some trouble trying to stream data to my plot.ly graph:
https://plot.ly/62/~Trollgeir/
The API:  https://plot.ly/streaming/

I am able to post messages that get recorded into the stream 
live, although right after curl uploads it, it just seems to wait 
for a response it's not getting, and eventually timeouts. Does 
anyone have any advice?

auto client = HTTP("stream.plot.ly");
client.addRequestHeader("plotly-streamtoken","e8bg6omat6");
client.verbose = true;

string msg = "{ \"x\": 500, \"y\": 500 } \n";
client.postData(msg);
client.perform;
