choose that configuration for static files:
location ~ .*\.(js|css|gif|jpg|jpeg|png|bmp|swf)$ {
expires 6h; -sharp
}and this configuration
location ~ .*\.(js|css|gif|jpg|jpeg|png|bmp|swf)$
{
proxy_pass http://app;
expires 6h;
proxy_cache tem;
proxy_cache_valid 200 1h;-sharp2001
proxy_cache_valid 301 1d;-sharp301
proxy_cache_valid any 1m;-sharp
}which configuration should I use? For dynamic requests, is it necessary to use the proxy_cache module to maintain direct access to the cache for a period of time?
