YUI().use("cache-offline", function(Y) {
    var cache = new Y.CacheOffline({
        sandbox:"6-hr-cache", // Pass in a unique identifier
        expires:21600000 // Expire data after 6 hours
    });
 
    // Add entries to the Cache
    cache.add("key1", "value1");
    cache.add("key2", "value2");
 
    // Retrieve a cached entry
    var cachedentry = cache.retrieve("key1");
 
    // Cached entry is an object with the following properties
    alert("cached key: " + cachedentry.request +
        " cached value: " + cachedentry.response +
        " cached at: " + cachedentry.cached +
        " expires at: " + cachedentry.expires);
