| <pre>public class <span class="typeNameLabel">TryFilesFilter</span> |
| extends java.lang.Object |
| implements javax.servlet.Filter</pre> |
| <div class="block">Inspired by nginx's try_files functionality. |
| <p> |
| This filter accepts the <code>files</code> init-param as a list of space-separated |
| file URIs. The special token <code>$path</code> represents the current request URL's |
| path (the portion after the context path). |
| <p> |
| Typical example of how this filter can be configured is the following: |
| <pre> |
| <filter> |
| <filter-name>try_files</filter-name> |
| <filter-class>org.eclipse.jetty.fcgi.server.proxy.TryFilesFilter</filter-class> |
| <init-param> |
| <param-name>files</param-name> |
| <param-value>/maintenance.html $path /index.php?p=$path</param-value> |
| </init-param> |
| </filter> |
| </pre> |
| For a request such as <code>/context/path/to/resource.ext</code>, this filter will |
| try to serve the <code>/maintenance.html</code> file if it finds it; failing that, |
| it will try to serve the <code>/path/to/resource.ext</code> file if it finds it; |
| failing that it will forward the request to <code>/index.php?p=/path/to/resource.ext</code>. |
| The last file URI specified in the list is therefore the "fallback" to which the request |
| is forwarded to in case no previous files can be found. |
| <p> |
| The files are resolved using <code>ServletContext.getResource(String)</code> to make sure |
| that only files visible to the application are served.</div> |
