NGINX Naxsi rules "Directory traversal IDs:1200-1299"

[gdur]

Actually looking for something else I discovered that in the /usr/local/etc/nginx/naxsi_core.rules file the rule #MainRule "str:/" "msg:slash in args" is commented out with "#" while in the Naxsi WAF policy settings page this feature has been enabled. Does anyone knows what the reason could be? Or is this a bug?
