Prefetch

Proactively warm up CDN caches by fetching files from your origin before user access, ensuring fast delivery and avoiding cache misses.

Prefetch prepares selected content in the CDN cache before normal user traffic requests it. This can reduce the impact of initial cache misses for content that is expected to receive traffic.

You can initiate Prefetch operations from the Medianova Control Panel or via the API.

When to Use Prefetch

Use Prefetch when:

• Content should be prepared in cache before a scheduled release or event.

• Large static or media files are expected to receive traffic.

• Selected assets should be cached before users begin requesting them.

• You want to reduce initial cache-miss requests to your origin.

Path Format

Enter paths without a domain and start each path with /.

For example:

/myimages/subfolder/image.png

Multiple paths can be submitted in the same Prefetch operation. Enter one path per line or separate paths with commas.

How Prefetch Works

When you submit a Prefetch operation, the CDN retrieves the specified content from the configured source and prepares it for cached delivery according to the CDN Resource's caching configuration.

The resulting cache behavior remains subject to the caching rules configured for the resource.

Use Prefetch for content that is eligible for caching. Content excluded from caching by the CDN Resource configuration cannot benefit from cache preloading in the same way.

Recent Prefetches

The Recent section displays Prefetch operations performed for the selected CDN Resource and the result of each path.
