4. Server level 404 error

One may get a 'page not found' when a request is made to the server for a resource that is outside of any registered contexts. As an example, you have a domain name pointing to your public server IP yet no context is registered with jetty to serve pages for that domain. As a consequence, the server, by default, will give a listing of all context running on the server.

One of the quickest ways to avoid this behavior is to create a catch all context. Create a "root" web app mapped to the "/" url. Have the index.html redirect to whatever place with a header directive.
