Nginx – Turn on Gzip for combined JS or CSS files without file extension

gzipnginx

I'm trying to configure GZip on my nginx server. It works for files with an file-extension.

To make a decision what kind of file is served over the network, Nginx does not analyze the file contents … Instead, it just looks up the file extension to determine its MIME type

So when I have a combine css file without a file extension it doesn't know it needs to be gzipped and serves it plain.

Is there a way to let nginx know that everything served from a specified location always needs to be gzipped. With or without an file extension?

I've got it working:

    location /files {
      types         { } 
      default_type  text/css;

      gzip  on;
      gzip_min_length  1;
      gzip_proxied     any;
      gzip_types       text/css;
      gzip_disable "MSIE [1-6]\.(?!.*SV1)";
      gzip_comp_level  6;
    }

And test:

curl -v localhost/files/test1
* About to connect() to localhost port 80 (#0)
*   Trying ::1...
* Connected to localhost (::1) port 80 (#0)
> GET /files/test1 HTTP/1.1
> User-Agent: curl/7.29.0
> Host: localhost
> Accept: */*

File without extension was sent as text/css mime. Or what do you need? text/html?

Now test gzip:

curl -H "Accept-Encoding: gzip" localhost/files/test1 | gunzip
