GLOBAL data per HTTP/Session request?

Question

QUESTION:

Is there any way to create a variable storage in per session/http request? The variable must be globally accessible and different

Answer 1

You can an unstable feature: nodejs domains

I do this on top of my head so read the docs and figure out really how it works ;)

Create a middleware high up in the hierarchy that will create a domain and run the remaining request handlers in the context of that domain:

app.use(function(req, res, next) {
  var domain = domain.create();
  domain.req = req;
  domain.run(next);
});

Then anywhere in your handlers, you can access the current request with:

var req = process.domain.req;

Again, read the docs, I'm really not sure about all this but this is one approach!
