Cookie Base Cache

Control CDN caching behavior by varying cache entries based on specific cookie values.

The Cookie Base Cache feature allows you to include selected cookies in the CDN cache key for Dynamic Content Acceleration resources. This ensures that different user sessions or states receive the correct cached response without disabling caching entirely.

This feature is available only for Dynamic CDN Resources.

How Cookie Base Cache Works

When Cookie Base Cache is enabled:

• The CDN inspects incoming requests for the configured Cookie Key values.

• The specified cookies are included as part of the cache key.

• Requests with different cookie values are cached separately.

• Requests without the configured cookies follow the default cache behavior.

This allows dynamic and personalized content to be cached safely without serving incorrect responses across users.

Configure Cookie Base Cache

You can configure this feature from the Medianova Control Panel.

1

Open the Caching Settings

Go to CDN → CDN Resources, select a Dynamic CDN Resource, and open the Caching tab.

2

Enable Cookie Base Cache

Set Status to On.

The cookie input field becomes active.

3

Define Cookies

Enter the cookie name:

• Cookie Key — Name of the cookie to include in the cache key

Use the + button to add multiple cookie keys if required.

4

Apply the Configuration

Select Submit to save and apply the changes.

• Each unique cookie value creates a separate cache entry.

• Cookie matching is based on the cookie name only; values are evaluated dynamically.

• This feature affects cache key generation, not cache bypass.

• Use together with Disallow Cookie Base Cache for advanced session-aware caching strategies.

• Adding too many cookies may increase cache fragmentation.

Common Use Cases

• Cache dynamic pages per user role or session type

• Serve different cached responses for logged-in vs logged-out users

• Safely cache HTML or JSON responses that depend on cookie state
