Genie 7110 manual Cache, Shared Feature Set Caching, Openwave Caching

Cache 13

Cache management is important for allowing quick access to previously viewed cards and controlling the display of time-sensitive content.

Shared Feature Set: Caching

■Do not leave time-sensitive data, such as stock quotes, in the cache.

■Use a cache-control directive to specify how long a deck should persist in the cache of a device.

A cache-controlled directive can prevent users from accessing outdated time-sensitive information, such as weather, traffic, or a stock quote. Cache-control directives are at a deck level rather than a card level.

Example 13-1

<meta http-equiv="Cache-control" content="max-age=600" forua="true"/>

In Example 13-1,the value 600 represents the number of seconds the data should be marked as valid the cache.

■Do not build an application that relies on information residing in the cache.

Openwave Caching

■The default TTL (time to live) for a deck is 30 days or until memory is exhausted.

■Allow the browser to prefetch the next deck when the user is likely to access the next card.

For applications providing textual information that users are likely to access in sequence, such as news or email.
