Hi,
Jean-Francois can you recall what the developer needs to do with
Atmosphere to support simple non-blocking async responses? IIRC you
blogged about it?
E.g. so a developer can do something like this:
to return a simple async response e.g.:
public void get(AsyncResponse ar) {
// create new thread wait on IO then set Response on ar
// return immediately
}
