    Default:	—
    Context:	http

#### 2.proxy\_cache配置语法 ####

        server 116.62.103.228:8001;
        server 116.62.103.228:8002;
        server 116.62.103.228:8003;
    }
    
    proxy_cache_path /opt/app/cache levels=1:2 keys_zone=imooc_cache:10m max_size=10g inactive=60m use_temp_path=off;

server \{  
listen 80;  
server\_name localhost;

location / {
        proxy_cache off;
        proxy_pass http://imooc;
        proxy_cache_valid 200 304 12h;
        proxy_cache_valid any 10m;
        proxy_cache_key $host$uri$is_args$args;
        add_header  Nginx-Cache "$upstream_cache_status";  
        
        proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
