[Plugin: Wordfence] Nginx with 2 conf

Hi,

A. I have 2 configurations files for nginx:
wordpress_http.conf for port 80 standard http
wordpress_https.conf for port 443 secure https

Does this mean I have to enter the information described in the following blog entry twice, e.g. once per configuration file? Or only in the http configuration file ?

B. In the file, there are many lines with:
location ~ /site/wp-content/wfcache/somethingelse
Is ‘site’ a parameter that will be replaced automatically by nginx ?

Or does it have to be adapted?
Should I replace it with:
location ^~ /wp-content/wfcache/somethingelse
