Thank you for your feedback on the docs. The “rate” parameter is assumed to be obligatory, though the syntax (http://nginx.org/r/limit_req_zone) may be constructed in a way to make it optional. For a common use case, the current behaviour is considered correct here, so the documentation would also be correct. I wouldn’t expect much changes here but let’s leave the latter to developers.

Best regards,
yar
