Is there a way to block a host if it makes too many requests per second?

Thanks!

Limit req module allows to delay/reject requests which are above  
certain threshold, see here:

There are not way to block hosts permanently after exceeding  
threshold. Usual aproach is to use fail2ban or something like to  
block them on your firewall if it keeps exceeding limit\_req  
thresholds (e.g. based on limit\_req erros in error\_log.

## For now, I think NginX can only limit by bandwidth usage (CMIIW) If you want to limit by request(s) per second, you can use 3rd party program (eg: firewall)
