Forum: NGINX Intermittent 404s when requesting a CSS file

Hi,



Just installed nginx and I am also using php5-fpm on Ubuntu.

I created a very simple php page that has a css stylesheet reference at 
the
top the of the generated HTML.



Every 2 or 3 requests however the browser request for the css file 
returns a
404 (nginx 404). When that happens in the response headers I see:



X-Powered-By  PHP/5.3.10-1ubuntu3.4



Which I think means that nginx sent the request to the php service 
instead
of serving the css file itself.



Can someone help me figure out why this is happening? ( see below for my
nginx default.conf )

    listen       80;

    server_name  localhost;

    root /home/gustavo/nginx/html;



                location ~* /css/.*\.css$ {

                                add_header Content-Type text/css;

                }



                location ~ \.js {

                                add_header Content-Type
