无法处理与nginxcaching用户login会话

我们遇到了用户login会话的问题，这是由于nginxconfiguration文件的caching。我们的应用程序在cakephp中开发。用nginx不可能停止caching特定的文件。请find下面的nginx conf文件，并build议用nginx处理用户login会话的最佳方法

其实你只提供了一小段你的Nginxconfiguration，但似乎你正在混合Nginx的caching选项。所示的proxy_no_cache选项用于Nginx的Web代理function（将请求转发给另一个Web服务器）。

关于本地托pipe的静态文件（如图片，CSS，JS …），请允许Nginx通过使用expires选项发送适当的caching标题。

关于PHP应用程序，您可以使用Nginx的FastCGIcaching。您也许知道，Nginx会将请求转发到PHP守护进程，如PHP-FPM。整个PHP魔法发生在这个PHP-FPM守护进程中，Nginx只会得到最终的响应，将它发送回客户端。

PHP应用程序现在可以决定在这个响应中包含caching头文件。如果允许caching（例如公共页面），PHP可能会返回一个Cache-Control标头以允许caching。

 <?php ... header('Cache-Control: public, max-age=3600'); ... ?>

如果不允许cachingPHP可能会返回一个不同的Cache-Control头来拒绝caching：

 <?php ... header('Cache-Control: private, no-store, max-age=0'); ... ?>

如果您的PHP应用程序能够发送适当的caching头，则可以使用以下configuration使用Nginx FastCGIcaching：

 fastcgi_cache_path /tmp/fastcgi_cache levels=1:2 keys_zone=phpfpm:64m inactive=24h max_size=512M; server { listen 80; server_name www.mysite.com; root /var/www/xyz; index index.php index.html; # check for static files and deliver, for everything else use /index.php location / { try_files $uri $uri/ /index.php; } # set caching header for static files location ~* \.(jpg|jpeg|gif|png|css|js|ico|svg|ttf)$ { access_log off; log_not_found off; expires 30d; } # set caching header for asset files, don't exec index.php just show 404 location ^~ /assets/ { try_files $uri =404; access_log off; log_not_found off; expires 30d; } # PHP handler, allow FastCGI caching location ~ \.php$ { access_log /var/log/nginx/access.log combined; include fastcgi_params; fastcgi_keep_conn on; fastcgi_pass unix:/run/php/php5.6-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_cache phpfpm; fastcgi_cache_use_stale updating error timeout invalid_header http_500; } }

如果您的PHP应用程序无法发送正确的caching标题，则可以强制caching或覆盖错误的caching标题。注意，这可能会导致向公众发布私人数据！

结论

它应该永远是Web应用程序（这里是一个PHP应用程序）定义哪个页面caching，哪些不是。使用networking服务器（Nginx，Apache或其他）来做出这个决定就像使用防撞屏障从外面控制汽车。它工作，但使用方向盘更聪明。
