How do I configure caching in Nginx?

To configure caching in Nginx, you can use the proxy_cache directive. First, define a cache path in your configuration file.

What directives do I need to set for caching?

You need to set proxy_cache_path, proxy_cache_key, and proxy_cache_use_stale among others, depending on your needs.

Can you give me an example of a basic configuration?

Sure! Here's a simple example:

http {
    proxy_cache_path /tmp/cache levels=1:2 keys_zone=my_cache:10m;
    server {
        location / {
            proxy_cache my_cache;
            proxy_pass http://backend;
        }
    }
}

How can I check if caching is working?

You can check the response headers for X-Cache-Status. If it shows HIT, caching is working.
