尝试打开 Nginx gzip 功能以节省一些带宽，但没有运气。搜索几个小时仍然无法使其工作。

Nginx 由Passenger 安装。以下是我服务器中有关 Nginx 的信息：

nginx version: nginx/1.4.1
built by gcc 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) 
TLS SNI support enabled
configure arguments: --prefix=/opt/nginx --with-http_ssl_module --with-http_gzip_static_module --with-http_stub_status_module --with-cc-opt=-Wno-error --add-module=/home/lijc/.rvm/gems/ruby-1.9.3-p392@rails3.2/gems/passenger-4.0.2/ext/nginx

Nginx.conf：

worker_processes  1;  
events {
    worker_connections  1024;
}

http {
passenger_root /home/lijc/.rvm/gems/ruby-1.9.3-p392@rails3.2/gems/passenger-4.0.2;
passenger_ruby /home/lijc/.rvm/wrappers/ruby-1.9.3-p392@rails3.2/ruby;

include       mime.types;
default_type  application/octet-stream;
sendfile        on; 
client_max_body_size 100m;
keepalive_timeout  65; 

gzip                                on; 
gzip_min_length                     1k; 
gzip_disable                        "MSIE [1-6]\.";
gzip_http_version                   1.1;
gzip_types                          text/plain text/css application/x-javascript application/xml application/json application/atom+xml application/rss+xml;
gzip_vary                           on; 

server {
    listen       80; 
    server_name  localhost;

    root /home/lijc/web/rails/jasli2team/evolution/public;
    passenger_enabled on; 
}
}

然后重启 Nginx 和Passenger。但是使用 Chrome 开发工具。我的网站返回的标题仍然不包括Content-Encoding:gzip

这是我的网站返回的标题：

我不知道出了什么问题或遗漏了什么。任何帮助将不胜感激。
