You can try to use the “nginx_refactoring” branch from here: https://github.com/SpiderLabs/ModSecurity/tree/nginx_refactoring or from here: https://github.com/defanator/ModSecurity/tree/nginx_refactoring There was a number of issues affecting nginx, fixed in those branches. Hope this helps. _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
