We have tasks in java web-app that take a long time in completing and before the time the task completes the request times out and page cannot be displayed happens. We are think of setting a async redirection servlet that acts as a front-controller redirecting the request to the appropriate action classes and while the request is being served the servlet keeps sending a heartbeat every minute or so, until the request is completed by the corresponding action classes. Has anybody implemented something similar using asynchronous servlet 3.0? Also is this possible? I understand that this is similar to server push. Thanks for guidance.
