that will also work in this instance.
you won't however see it slowly send the response as you do on http://trombone.zapto.org/, as cloudflare seems to block until it received the full response from the backend.
No affiliation with cloudflare other than I use them for several sites.
In the meantime, if you want to visit the page directly without CloudFlare, go to http://trombone.zapto.org instead.
I hope you don’t regularly make such selfish requests to potential DoS victims due to your own arrogance / ignorance.
