NGINX Cookbook

How to do it...

In order to enable the cache, first we need to define where to store the cached files. This needs to be set outside the server block directive and is best stored in the main nginx.conf file. Here's the directive required:

proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=cache:2m 

Make sure you create the directory and that NGINX has write access.

Then, we can create a block directive to use this cache:

server { 
    listen       80; 
    server_name  cached.nginxcookbook.com; 
    access_log  /var/log/nginx/cache-access.log  combined; 
 
    location / { 
        proxy_pass http://localhost:8080; 
        proxy_cache cache; 
        proxy_set_header X-Real-IP  $remote_addr; 
        proxy_set_header X-Forwarded-For $remote_addr; 
        proxy_set_header Host $host; 
    } 
}
