Shared Cache

Define whether a CDN resource uses its own cache or shares a common cache structure across multiple accounts using the Domain Cache Key.

Shared Cache allows multiple accounts or domains to use the same cache structure by applying a Domain Cache Key. When set to Share, identical content is cached only once and served across participating accounts, improving efficiency and reducing redundant origin requests. When set to Default, each account maintains its own isolated cache.

You can manage Shared Cache in the Medianova Control Panel or via API.

Log in to the Medianova Control Panel, select a CDN resource in the CDN section, and navigate to the Caching tab.

Configure Shared Cache

1

Select the Cache Status

Choose one of the following options:

• Default — Each account maintains a separate cache structure.

• Share — Cache is shared across accounts using the Domain Cache Key.

2

Submit the Configuration

Click Submit to apply the selected cache status.

Behaviour

• When set to Share, CDN edge nodes use the same cache namespace for resources that match the Domain Cache Key.

• Cache hits increase across accounts that serve identical content.

• Changing the status does not purge existing cache; behavior changes apply to future caching operations.

• When set to Default, each account's cache becomes isolated again.

FAQ

Does enabling Shared Cache expose content from one customer to another? No. Shared Cache only applies where explicit Domain Cache Key alignment exists and is intentionally configured.

Does switching from Default to Share purge existing cache? No. Existing cached content expires naturally according to its TTL.

When should Shared Cache be enabled? It is beneficial when multiple accounts deliver the same static assets (e.g., white-label platforms, partner domains).
