Limiting concurrent requests to domain

Dear Cloudflare Community,

I’m interested in implementing a limit on the number of concurrent requests to a particular domain (zone) within Cloudflare. While I’ve extensively reviewed the documentation and currently utilize Page Rules, Cache Rules, and Origin Rules, I haven’t been able to find a straightforward method for imposing a general limit on concurrent requests to a domain.

I’m aware of the capability to limit concurrent requests per IP address, but my requirement extends to applying a global limit across all requests to the domain, rather than on a per-IP basis.

I understand this might be an unconventional request, as it’s part of an experimental setup I’m working on. If anyone within the community has experience or insights on achieving such a limitation within Cloudflare, I would greatly appreciate any guidance or suggestions you could provide.

Thank you in advance for your assistance.
Best regards,
Lisandro

It sounds like you’re asking about something like Waiting Room.

Or Advanced Rate Limiting on an Enterprise plan, which can do exactly what you’re describing.
