Something is injecting a slash after any static file response , server is nginx

Check the mime.types file in Nginx’s config directory (if you’re on Linux this is typically /etc/nginx/). If there’s no MIME type file, check to see whether MIME types are declared inside nginx.conf. If not, you may need to create a mime.types file and include it in nginx.conf.

Here’s the information on the Nginx wiki about MIME types: http://wiki.nginx.org/HttpCoreModule#types
