Hi Rob Interesting project. I havn't looked at the machine learning part of it, although that also sounds interesting, but at first I was more interested in the long polling aspect of your application. I was looking at something similar but in the end I decided that given my use case (mostly a single client polling) it didn't make much sense to use nginx. I'm guessing that in your architecture, nginx makes more sense because you have a lot of clients polling the same interface? That way you know that it is much more likely that there will be at least one subscriber left for a message when the server actually has something to send. And I guess the way the back-end knows that there is still someone that wants to know about a message is that nginx says that there is still clients waiting when it delivers the message. Could you maybe elaborate a bit more on this? > https://github.com/rplevy/sayoperation > > The application itself is online (for now) at: > > http://www.robertplevy.net/sayoperation/ > > A little bit of context is necessary here.
