How to abort controller action in play framework 2.1 when client cancel request or client socket is closed?

Question

I am testing play framework 2.1 to check what happen when client cancel request or socket is closed from client side. I created this simple program:

package controllers;

import play.;
import play.mvc.;

import views.html.*;

public class Application extends Controller {

public static Result index() {

    try{
        for(int i=0;i<1000;i++){
            Thread.sleep(10000);
            System.out.println(i+"\n");
        }
    }catch(Exception e){
        System.out.println("\nexcepción capturada");
    }
    return ok(index.render("Your new application is ready."));
}

}

If I cancel request from client (google chrome) the loop isn't aborted. I think this could be a problem in real world application, not making a loop, but doing a "heavy" query to database.

Answer 1

Since there was no answer I asked on the google group for play https://groups.google.com/forum/?hl=en#!topic/play-framework/POvFA3moXug and here is what James Roper from Typesafe said:

Play offers no such feature. However, there are other ways to achieve the same thing, for example, if you have a long running request, you could do it as a websockets request, which let's you easily detect when the client navigates to a different page.

The latest release as of today is play-2.2.0-RC1 (in case they add support later).
