I would suggest you load the Zinc WebSockets addon package: https://github.com/svenvc/docs/blob/master/zinc/zinc-websockets-paper.md In particular, look at ZnWebSocket class>>#to: where after an initial request/response interaction, the actual connection used in the client is taken and used to run a completely different protocol. I guess in your case you would then keep on reading responses. But it might be simpler than that, if the server returns an actual infinite response, you could ask for ZnClient>>#streaming: true and use the resulting ZnStreamingResponse's contents (a stream) to keep on reading. Good luck and let me know how it goes, I am pretty sure we can get this working ! If you can tell me how I can access such a response with my twitter account, I can try as well. Sven
