Re-establishing push notification channels via user identifiers

摘要

Embodiments enable recovery of push notification channels via session information associated with user identifiers. A proxy service creates session information describing push notification channels (e.g., subscriptions) for a user and associates the session information with a user identifier. The session information is stored in a cloud service or other storage area separate from the proxy service. After failure of a user computing device or the proxy service, the session information is obtained via the user identifiers and the push notification channels are re-created with the session information. In some embodiments, the proxy service enables delivery of the same notification to multiple computing devices associated with the user identifier.
