Calling unique url not more then 1 time per 5 seconds

Server NGINX
1

Hi,

Assuming I have an url like /payout/[hash] , where hash is something
unique,
and I want to make, that on nginx level it’s checked that this url is
called
not more then 1 time per 5 seconds. 1st time it should be processed by
proxy_pass, all the other times it should be replied 403.

Could someone tell me which approach I should use? Is that possible to
do
that using nginx?

Any thoughts are appreciated.

Regards,

Yes, it’s possible:
http://nginx.org/r/limit_req_zone

If a rate of less than one request per second is desired, it is specified in
request per minute (r/m). For example, half-request per second is 30r/m.

This is for the case you need to impose a limit of 12r/m per the entire
“/payout/” location.

But if you mean 12r/m per individual hash, that might be tricky.

It’s not tricky. It can be achieved by configuring $uri as the key.
