15  * <p>Creates views which result in HTTP redirects.</p>
16  *
17  * <p>Views will handle the model in the following way:</p>
18  *
19  * <ul>
20  * <li>
21  * If the model is a String, that is used as the base URL
22  * and the path attribute is ignored.
23  * </li>
24  * <li>
25  * If the model is a Map, the key/value pairs are converted
26  * into parameters for the target URL. This behavior is
27  * deprecated; you should use ControllerContext.setParam()
28  * instead.
29  * </li>
30  * </ul>
31  *
32  * <p>Params set on the ControllerContext will become
33  * query parameters.</p>

35  * <p>Redirect views cannot have transforms and have no
36  * attributes other than "path".</p>
