We need the site's root location (for example: "https://localhost:8443/" ) to automatically redirect to the the context root "https://localhost:8443/acorn" as setup for one of the web projects found in our application.

In my application.xml I have the following settings for one of the war projects in the EAR file:

<module>
    <web>
      <web-uri>fnds-admin-web-1.0.0.war</web-uri>
      <context-root>acorn</context-root>
    </web>
</module>

I added a file undertow-handlers.conf to the /WEB-INF/ folder of that specific web project, with the following line (hoping that it would do the trick):

 path['/'] -> rewrite['/acorn']

However, the default Wildfly welcome page was still shown when entering "https://localhost:8443/" in the browser and entering "https://localhost:8443/acorn" in the browser now resulted in an 404 - Not Found error page.

Perhaps my undertow-handlers.conf is invalid?
