This is a test page to demonstrate how to add a custom HTTP header using .htaccess. To view the custom header, open the browser's developer tools, open the Network tab, then refresh the page. Select the "http-header" resource on the left pane (that's the name of this directory, which could be anything). You can then view the response headers, in which case you should see the "funky-music" header with a parameter/value pair of "getdownand=boogie".
