And again - NGINX is giving me many Questions today :)

Like always, I already tried around for a while, but cant seem to fix this issue:

I just configured NGINX to handle my .css files equal to my .php files (to parse PHP tags inside the CSS file). This works perfectly, and the file is found and delivered.

I could debug it with FIrebug, and everything is OK (it displays the contents of the .css inside the opened <link> tag). So, everything working, right? Wrong.

It has the CSS, but it does not interpret it! What I mean by this: apparently, the file-type of the CSS (or aplication-type, whatever) is wrong. The Page can access the CSS, but doesnt bother at all to actually use it.

What I checked / tried:

• There are no PHP errors inside of the .css, so that one is out
• The .css is accessible. I can call the URI manually, or check if the included URL finds it: both works
• The .css has no syntax errors (i switched to a css that just has body {background-color: #000; }
• It works whitout NGINX
• I deleted the browser cache / restarted NGINX after config rewrites

Here the configuration:

server {
        listen      80;
        server_name localhost;

        access_log  /var/log/nginx/board.access_log;
        error_log   /var/log/nginx/board.error_log warn;

        root        /var/www/board/public;

        index       index.php;
        fastcgi_index   index.php;

        location / {
            try_files $uri $uri /index.php;
        }

        location ~ (\.php|\.css)$ {
            try_files $uri =404;

            include /etc/nginx/fastcgi_params;
            #keepalive_timeout 0;           
            fastcgi_param   SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            fastcgi_pass    127.0.0.1:7777;
        }
    }

Firebug 'Network' Response Header:

Connection  keep-alive
Content-Encoding    gzip
Content-Type    text/html

Server  nginx/1.0.5
Transfer-Encoding   chunked
X-Powered-By    PHP/5.3.6-13ubuntu3.7

I think I just answered my own question. Is the Content-Type text/html the problem? How can I remove that?

My personal guess is that I have to use this in some way

include /etc/nginx/mime.types;
default_type application/octet-stream;

But I'm not sure... anyone an idea how to solve this?

TLDR; CSS file is delivered correctly, but it doesnt seem to be 'used' as CSS from the browser. (Tested, works on apache)
