404 should be silent if needed

[bastien-roucaries]

ultra low priority some admin prefer to redirect 404 to something else for security point of view

Right now, a warning is written to stderr when an invalid path is requested, and a 404 Error page is served. Do you suggest to suppress the error page, and not respond anything, just close the connection when 404 would be the response?

You are right removed the bad advice

Good advice will be to return

• header("HTTP/1.1 404 Not Found");
• return a html header file and load the body from /404.xml with a javascript plugin.

But it is superlow priority

Or better return pure html5 and use import from 404.html https://www.html5rocks.com/en/tutorials/webcomponents/imports/
