gzip not working in nginx, what's the problem?

Question

Nginx

There is one server with these gzip settings:

##
  # Gzip Settings
  ##

  gzip on;
  gzip_disable "msie6";
        gzip_min_length 1024;
  gzip_http_version 1.0;

  
  gzip_proxied any;
  gzip_comp_level 6;
  gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

When the page is opened, there is no compression, if you look at the headers of the issued page, then there is nothing about it:

Connection:keep-alive
Content-Type:text/html; charset=UTF-8
Date:Fri, 21 Nov 2014 17:31:18 GMT
Server:nginx/1.6.2
Transfer-Encoding:chunked
X-Powered-By:PHP/5.5.19-1~dotdeb.1

what is the problem here? And static files with the same headers are not compressed.
When checked by this service: www.gidnetwork.com/tools/gzip-test.php shows
that there is compression, although when viewing the page in a browser, there is no Content-Encoding: gzip header. And the size of the downloaded file (page) and the content from it are the same, i.e. there is no compression.

Answer 1

Take a look at the definition of nginx MIME types - mime.types file. For js files, recent versions use application/javascript instead of text/javascript. If so, change gzip_types to match this definition.

Answer 2

1. Content-Type:text/html is not listed in gzip_types;
2. You may be getting less than 1024 which is specified in gzip_min_length.

Answer 3

Reconsider or everything is correctly indicated:
yapro.ru/web-master/apache/nastroyka-gzip-v-nginx.html

Answer 4

Is the client you're checking with exactly sending an Accept-Encoding: gzip header? Do you have compression on toster.ru?
Perhaps someone cuts out this header, for example, in ancient times, the outpost firewall did this.
