onRequest

public void onRequest(AtmosphereResource resource)

Description copied from interface: AtmosphereHandler

When a client sends a request to its associated AtmosphereHandler, it can decide if the underlying connection can be suspended (creating a Continuation) or handle the connection synchronously.

It is recommended to only suspend requests for which HTTP method is a GET and use the POST method to send data to the server, without marking the connection as asynchronous.

Parameters:

resource - an AtmosphereResource
