End-to-end validation in a push environment

A method comprising:

• receiving a request from an application to register an application endpoint, said application executing on a computing device, said computing device configured to receive messages from a service via a gateway;
• registering the application endpoint with the gateway responsive to the received request, wherein the gateway defines a registration timeout value, and wherein the application subscribes the application endpoint to receive the messages from the service;
• calculating, relative to a current time, an elapsed time since said receiving;
• and
• notifying the application of a timeout condition when the calculated elapsed time exceeds the registration timeout value without one of the messages being received from the service, wherein the application re-registers the application endpoint and re-subscribes with the service responsive to said notifying to receive the messages.

One or more computer-readable media having computer-executable components, said components comprising:

• a communication component for interfacing between a computing device and a gateway, said computing device configured to receive messages from a service via the gateway;
• a registration component for registering an application endpoint with the gateway, said application endpoint being associated with an application executing on the computing device, wherein the application subscribes with the service to receive the messages;
• a timeout component for monitoring the registration by the registration component, wherein the timeout component notifies the application of a timeout condition after a predefined period of inactivity responsive to the registering by the registration component;
• and
• an inactivity component for receiving notice of inactivity from the gateway after expiration of an inactivity timeout value maintained by the gateway, wherein the inactivity component notifies the application of the inactivity responsive to the received notice of inactivity.
