Remarks
Setting an expiration time for periodic updates
Tiles expire by default after three days. If your notification content has a significantly different useful lifespan—shorter or longer—you can explicitly set an expiration time for each notification, and it is a best practice to do so. This prevents stale or irrelevant content from remaining in the queue. This is especially important if the user's machine loses Internet connectivity for a long period of time.
For example, during active trading, it would be advisable for a stock app to set the expiration on a stock price notification to twice that of your polling interval. For example, the notification would expire one hour after it is sent if you poll for an update every half-hour. In the case of a news app, an expiration of one day for a tile that shows the top daily news would be appropriate.
In the case of periodic notifications, the expiration time is set in the X-WNS-Expires header of the notification's HTTP response message. The expiration time is expressed as an HTTP-date, which uses one of the formats shown in these examples:
- Sun, 06 Nov 1994 08:49:37 GMT
- Sunday, 06-Nov-94 08:49:37 GMT
- Sun Nov 6 08:49:37 1994
For more information on the HTTP-date format, see the World Wide Web Consortium (W3C) Protocol Parameters document.
