Common nginx configuration for all Vhosts

Hi,

Currently I'm using the ngx_http_limit_req_module as follows for every single Vhost (by changing the zone name:

limit_req directive in the Custom Configuration under Content Tab

location ~* wp\-login\.php {

and the limit_req directive in the Custom Top Level Configuration under Advanced Tab

limit_req_zone $binary_remote_addr zone=cwwp:10m rate=3r/m;

I'd like to use one common for all the Vhosts.

I tried adding the limit_req directive in a file /etc/nginx.wp/restrictions.conf but when I tried adding the limit_req_zone directive nginx throws error.

Kindly help.

Peace
