    <p>The Cache Utility provides a basic caching mechanism for storing key/value pairs in local JavaScript memory.
</div>

<div class="example">
    {{>cache-basic-source}}
</div>

```
YUI().use("cache-base", function(Y) {
    // Configure Cache maximum size, expires in the constructor
    var cache = new Y.Cache({max:5, expires:3600000});

    // 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();
});
```
