This Jetty doco page https://www.eclipse.org/jetty/documentation/9.3.x/embedded-examples.html#embedded-split-file-server shows how to set up two context handlers which serve two different resource bases (eg. /var/www/docs and /var/www/api-docs) to the same path (eg. myurl.com/documentation).
A previous question showed how to do this with a ServletContextHandler: Serving static files from alternate path in embedded Jetty. You can add a Filter to a ServletContextHandler, but how do you add a Filter to a ContextHandlerCollection? For example an X-Frame-Options header?
Thanks!
