Cloudflare Research: Privacy Pass Size Experiment

On a small fraction of our challenge pages, we were running an experiment to measure the performance impact of larger Privacy Pass tokens.

What is the experiment?

For challenge pages that were part of the experiment, we sent a background POST to this page with a dummy token.

The experiment did not impact the security of your connection or the result of the challenge.
