    gzip_vary on;
    gzip_proxied any;
    gzip_comp_level 6;
    gzip_buffers 16 8k;
    gzip_http_version 1.1;
    gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

    proxy_cache_key $scheme$proxy_host$request_uri$cookie_US;

服务器配置

upstream some site {
  server unix:/webapps/some/run/gunicorn.sock fail_timeout=0;
}

server {
    listen   80;
    server_name server name;
    expires 7d;
    client_max_body_size 4G;

    access_log /webapps/some/logs/nginx-access.log;

    error_log /webapps/some/logs/nginx-crit-error.log crit;
    error_log /webapps/some/logs/nginx-debug.log debug; 
    location /static/ {
        alias   /webapps/some/static/;
    }

    location /media/ {

    }
    location ~* ^(?!/media).*.(?:jpg|jpeg|gif|png|ico|cur|gz|svg|svgz|mp4|ogg|ogv|webm|htc)$ {
        root root_path;
        expires 7d;
        add_header Pragma public;
        add_header Cache-Control "public, must-revalidate, proxy-revalidate";
        access_log off;
    }    
    location ~* ^(?!/static).*.(?:css|js|html)$ {

        add_header Cache-Control "public, must-revalidate, proxy-revalidate";
        access_log off;
    }     

    location / {

        proxy_cache one;
        proxy_cache_min_uses 1;
        proxy_cache_use_stale error timeout;

        # proxy_set_header X-Forwarded-Proto https;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        if (!-f $request_filename) {
            proxy_pass http://some;

而不是用 GET 注销请求，更改您的注销 View 以接受表单 POST .
POST不应缓存请求。

这具有额外的安全优势，可以防止用户使用 iframe 或恶意链接注销(即: https://example.com/logout/ ，假设您没有禁用 django 的 CSRF 保护)。

注意:有一个 ticket on django's bug tracker related to this issue .
