What’s the correct nginx config for cache-control and server-caching rules?

Asked on Oct 09, 2025

Answer

To optimize web performance with Nginx, setting appropriate cache-control and server-caching rules is essential. This involves configuring headers to instruct browsers on how to handle caching for different types of content.

<!-- BEGIN COPY / PASTE -->
    location ~* \.(jpg|jpeg|png|gif|ico|css|js)$ {
        expires 30d;
        add_header Cache-Control "public, no-transform";
    }

    location ~* \.(html|htm)$ {
        expires -1;
        add_header Cache-Control "no-store, no-cache, must-revalidate, proxy-revalidate, max-age=0";
    }
    <!-- END COPY / PASTE -->

Additional Comment:

Use "expires" to set how long resources should be cached by the browser.
"Cache-Control" headers provide more granular control over caching behavior.
Static assets like images, CSS, and JS can be cached for longer durations (e.g., 30 days).
Dynamic content like HTML should have caching disabled to ensure users receive the latest version.
Adjust paths and file types according to your specific needs and website structure.
