Re-configure Apache running the metrics website to redirect 404s to Tomcat
The metrics website consists of an Apache that serves some static content and redirects requests for dynamic content to Tomcat. But when Apache encounters a problem with static content, e.g., when requesting a non-existing file, it returns a 404 itself. Instead, Apache should show the same 404 error page that Tomcat would display. Users shouldn't even notice that the website is run by Apache and Tomcat. Very low prio.
