X-Forwarded-For

AspNetCoreRateLimit supports X-Real-IP but not X-Forwarded-For

https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Forwarded-For

Please note that X-Forwarded-For elements are comma-separated, with optional whitespace surrounding the commas. Only the first element is useful for us and this first element should be considered equivalent to X-Real-IP to the best of my knowledge.
