Digests

Each digest contains one or more entries which can be one of the following types:

• CacheOp--a command that invalidates an individual deck or an entire service in the UP.Phone cache.

• HDML--an HDML deck.

• Alert --a command that instructs the UP.Phone to beep or display a visual signal to notify the subscriber that information has been pushed to the phone.

• DeviceData--data downloaded to the UP.Phone and passed to device-dependent applications.

• Unknown--any other type.

The order in which entries are added to the Digest is significant; the browser processes the entries according to the order in which they appear in the digest. The browser stores all HDML decks from a digest in the cache, and then displays the first HDML deck in the digest.
