=== Default Handler

[[default-handler-metadata]]
==== Info

* Classname: `org.eclipse.jetty.server.handler.DefaultHandler`
* Maven Artifact: org.eclipse.jetty:jetty-server
* Javadoc: {JDURL}/org/eclipse/jetty/server/handler/DefaultHandler.html

[[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.
