Im running a Merb project base on Nginx + Passenger, when the application got error, it will raise 502 Bad Gateway page. so we want to customize the error page. so we add these to the configuration file: http{ server{ .... error_page 500 502 503 504 /500.html; location = /500.html { root /home/some_dir/; } .... } ] but it couldn't work,by ysorigin - Nginx Mailing List - English
