What is a Ray ID (Cloudflare)? : <p>Everytime I visit a website that is using Cloudflare's Under-Attack-Mode it shows me the usual text telling me to wait a few seconds until Cloudflare verified I am not a bot. Everytime I reload the page it changes my current Ray ID.</p>

<p>My Question: What is the purpose of a Ray ID? Is it some kind of Session ID?</p>

<p>Thanks.</p>
