<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();

});

```
