How to disable http TRACE method in jetty 9.4?

First note that that jetty is used by the monitor ONLY if you enable the "monitoring server" button on the CF Admin "server monitoring>monitoring settings" page. That simply enables accessing that monitor on that jetty port. Otherwise, you can access the CF monitor on the same port as the CF Admin.

And if you are NOT using that Jetty for that or any other use, then you can just disable it entirely. Or you can limit what IP address it listens on. Both can be done in the jetty.xml file. There's some discussion of modifying that here: ColdFusion Help | Work with Server Monitor

But if you NEED it enabled, then there's no discussion of disabling those option types you request. But here's the first result of searching for how to control options for jetty. Seems like it would work.

And as it indicates, the webdefault.xml file it refers to C:\ColdFusion10\cfusion\jetty\etc folder. But I have not tried it.
