limit_req_zone: How to apply only to some requests containing some string in the URL?

[Payam Chychi]

Maybe ive misunderstood but cant you very simply do this by injecting a cookie on the origina req page and then have nginx match, count it and apply rates? Or maybe im comicating it... If even possible
