Abstract: Techniques are described for updating resources provided to a user device, using subscription based polling. A user device may send initial requests for resource to a server, each initial request including a resource identifier and a subscriber identifier. In some cases, the subscriber identifier may uniquely identify the communication session. The server maintains subscription information correlated with the subscriber identifier, the subscription information listing which resources the user device has requested and which versions of the resources are currently available on the user device. Updates to the subscribed resources may then be provided to the user device in response to a request for updates that specifies the session identifier but that may not specify the particular subscribed resources.

Abstract translation: 描述了使用基于订阅的轮询来更新提供给用户设备的资源的技术。 用户设备可以向服务器发送资源的初始请求，每个初始请求包括资源标识符和订户标识符。 在一些情况下，订户标识符可以唯一地标识通信会话。 服务器维护与用户标识符相关的订阅信息，订阅信息列出用户设备已经请求哪些资源和资源的哪些版本当前在用户设备上可用。 然后可以响应于指定会话标识符的但是不指定特定订阅资源的更新请求，向用户设备提供对订阅资源的更新。
