+ * This call is asynchronous: the data may not be immediately available

+ * @param url The URL of the resource to insert
+ * @param data Response data to store for this resource. Data is expected to be uncompressed; internally, the cache will compress data as necessary.

+ * @param expires Optional "expires" response header
+ * @param etag Optional "entity tag" response header
