What is the Atmosphere Framework?

An AtmosphereHandler can be used to suspend, resume and broadcast. A Meteor can be used with existing Servlet or Servlet based technology like JSP, JSF, Struts, etc.

Terminology

• Suspend: The action of suspending consist of telling the underlying Web Server to not commit the response, e.g. to not send back to the browser the final bytes the browser is waiting for before considering the request completed.
• Resume: The action of resuming consist of completing the response, e.g. committing the response by sending back to the browser the final bytes the browser is waiting for before considering the request completed.
• Broadcast: The action of broadcasting consists of producing a message and distributing that message to one or many suspended responses. The suspended response can then decide to discard the event or send it back to the browser.
