| <h1 id="redirect-result">Redirect Result</h1> |
| |
| <p>Calls the <code class="language-plaintext highlighter-rouge">{@link HttpServletResponse#sendRedirect(String) sendRedirect}</code> method to the location specified. The response |
| is told to redirect the browser to the specified location (a new request from the client). The consequence of doing this |
| means that the action (action instance, action errors, field errors, etc) that was just executed is lost and no longer |
| available. This is because actions are built on a single-thread model. The only way to pass data is through the session |
| or with web parameters (<code class="language-plaintext highlighter-rouge">url?name=value</code>) which can be OGNL expressions.</p> |
| |
| <h2 id="parameters">Parameters</h2> |
| |
| <ul> |
| <li><code class="language-plaintext highlighter-rouge">location</code> (default) - the location to go to after execution.</li> |
| <li><code class="language-plaintext highlighter-rouge">parse</code> - true by default. If set to false, the location param will not be parsed for OGNL expressions.</li> |
| <li><code class="language-plaintext highlighter-rouge">anchor</code> - Optional. Also known as “fragment” or colloquially as “hash”. You can specify an anchor for a result.</li> |
| </ul> |
| |
| <p>This result follows the same rules from <code class="language-plaintext highlighter-rouge">StrutsResultSupport</code>.</p> |
