Traefik rate limiting on header name case sensitivity

My client sends a custom header X-FOO-bAR to the server that traefik sits in front of.

I have a rate limiting rule in place to rate limit on this header, and I define the rule in my docker compose file like so:


In the traefik logs, it looks like the header is getting cased to X-Foo-Bar

Do I need to make my rateLimit rule match the casing that traefik sets? Or is the traefik rate limiting case insensitive when it comes to headers?
