detect client abort in action

[Fabian Kessler]

How can I check whether the client aborted within a play action?
I'm looking for the equivalent to PHP's connection_aborted() http://php.net/manual/en/function.connection-aborted.php
Can I listen on that event, or check the status? On the request() object I did not see anything related to it, and all I could google is this unanswered question: http://stackoverflow.com/questions/15419269/how-to-abort-controller-action-in-play-framework-2-1-when-client-cancel-request

Hi Fabian,

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.

Regards,

James

Hi, James

Thank you for a great product.

And I have a question about this topic.

GlobalSetting.scala has the method, onRequestCompletion.

This callback seems to be called when connection disconnected or request handle finished.

And this callback perhaps seems to run on netty worker thread.

Can I use onRequestCompletion to detect connection abort?
