| ==== Info |

| * Classname: `org.eclipse.jetty.server.handler.DefaultHandler` |
| * Maven Artifact: org.eclipse.jetty:jetty-server |

| [[default-handler-usage]] |
| ==== Usage |
| |
| A simple handler that is useful to terminate handler chains with a clean fashion. |
| As in the example below, if a resource to be served is not matched within the resource handler the `DefaultHandler` will take care of producing a 404 page. |
| This class is a useful template to either extend and embrace or simply provide a similar implementation for customizing to your needs. |
| There is also an link:#error-handler[Error Handler] that services errors related to the servlet api specification, so it is best to not get the two confused. |
| |
| _____ |
| [NOTE] |
| The `DefaultHandler` will also handle serving out the `flav.ico` file should a request make it through all of the other handlers without being resolved. |
