YUI Library Examples: Cache Utility: Basic Caching

YUI().use("cache", function(Y) {
    // Configure Cache maximum size in the constructor
    var cache = new Y.Cache({max:5});
 
    // 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 a request property and a response property
    alert("cached key: " + cachedentry.request +
        "/cached value: " + cachedentry.response);
 
    // Flush the cache
    cache.flush();
});
