| * <p>This tag is used to create a URL.</p> |
| * |
| * <p>You can use the <param> tag inside the body to provide |
| * additional request parameters. If the value of a param is an Array or |
| * an Iterable all the values will be added to the URL.</p> |
| * |
| * <b>NOTE:</b> |
| * <p>By default request parameters will be separated using escaped ampersands (i.e., &amp;). |
| * This is necessary for XHTML compliance, however, when using the URL generated by this tag |
| * with the <s:property> tag, the <b>escapeAmp</b> attribute should be used to disable |
| * ampersand escaping.</p> |
| * |
| * <b>NOTE:</b> |
| * <p>When includeParams is 'all' or 'get', the parameter defined in a <param> |
| * tag will take precedence over any params included due to the includeParams attribute. For |
| * example, in Example 3 below, if there is a id parameter in the url where the page this |
| * tag is included like http://<host>:<port>/<context>/editUser.action?id=3333&name=John |
| * the generated url will be http://<host>:<port>/<context>/editUser.action?id=22&name=John |
| * because the parameter defined in the param tag will take precedence.</p> |
