如何使nginx緩存重寫資產？

Question

我使用的是cakephp1.3，一些資產是主題資產（js，img等），其他資產不是主題資產。

非主題資產緩存正確;但主題資產沒有得到正確的到期標題。我在位置塊中使用重寫來幫助查找主題資產，但由於某些原因，nginx不會應用正確的緩存標頭。

我附上了我的nginx配置下面的副本。有沒有人解決了如何緩存重寫的資產？

user nginx; 
worker_processes 2; 

error_log /var/log/nginx/error.log; 

pid  /var/run/nginx.pid;

是的，主題資產在CakePHP的速度較慢，所以一直也其官方文檔中描述here。

解決方案是通過使用try_files通過nginx提供這些主題資產。

下面是用於上述目的的例子nginx的配置：

# Serve CakePHP plugin assets directly 
location ~ /(.+)/(img|css|js|files)/(.*) { 
    access_log off; 
    expires 10d; 
    add_header Cache-Control public; 
    try_files $uri $uri/ /../plugins/$1/webroot/$2/$3 /../../plugins/$1/webroot/$2/$3 /index.php?url=$uri; 
}
