How can I check that the nginx gzip_static module is working?

Question

How can I check that nginx is serving the .gz version of static files, if they exist?

I compiled nginx with the gzip static module, but I don\'t see any mention of the .

Answer 1

I would disable automatic compression and log gzip_ratio:

http {
   gzip off;
   gzip_static on;

   log_format log_with_ratio "... $gzip_ratio ...";

   server {
      access_log /var/log/nginx/file.log log_with_ratio;
   }
}

Note, that you may override gzip, gzip_static and access_log per server and location levels.
