Using the Push Notification Sample Application
The push notification sample, which is included in the Microsoft Exchange Server 2010 SP2 Web Services Software Development Kit (SDK), consists of a client Web service and an application that establishes the subscription.
The client Web service must be published to a MicrosoftInternet Information Services (IIS) virtual directory before the subscription can be established. After the client Web service is set up, you can run the subscriber application from the command line. The subscriber application does not take any arguments. After the subscriber application runs, a subscription is set up on the Client Access server. The Client Access server will then send notifications to the client Web service.
Note
If there is a proxy server between the client Web service and the Client Access server, you will need to set a bypass list on the web.config file on the Client Access server. The XPath expression to this web.config file setting is /configuration/system.net/defaultProxy/proxy/bypasslist. For an example of this setting, see the Event Notifications topic.
