Middleware filter agent between server and PDA

摘要

A content server provides content to a first network device during a data synchronization between the two devices. A middleware filter selectively filters content provided by the content server such that selected content is provided to the first network device. The middleware filter is included within a second network device coupled between the content server and the first network device. The second network device acts as a proxy for the first network device to receive the content provided by the content server. The content is provided from the content server according to a subscription service between the content server and the first network device. The first network device is preferably a personal digital assistant (PDA) and the second network device is preferably a personal computer. Alternatively, the content server is coupled to the first network device, without the second network device coupled in between. In the alternative case, the middleware filter is included within the content server, and the content is selectively provided from the middleware filter, on the content server, to the first network device.

主权项

1. A network of devices to filter synchronized data, the network of devices comprising:
a. a content server to store content; b. a first network device; and c. a middleware filter coupled to the first network device and to the content server such that during a data synchronization, the content is received by the middleware filter from the content server according to the data synchronization, and the middleware filter is programmed to selectively filter the content resulting in filtered content and send only the filtered content to the first network device, wherein the middleware filter selectively filters in response to meta data within the content and one or more attributes of the first network device, wherein the meta data comprises a data type of the content, wherein the middleware filter performs an authorization before sending the content to the first network device.
