How to Prefetch

Perform Prefetch operations through the Control Panel or API to proactively cache files and deliver them instantly to end-users.

You can perform Prefetch operations directly from the Medianova Control Panel or via API. This guide explains both methods, helping you cache important assets in advance to reduce latency and improve performance.

Prefetch Cached Files

Prefetch allows you to proactively fetch and cache a specific file from your origin before any user requests occur. Use this feature to ensure that large or frequently accessed content is already cached in CDN edge locations, minimizing latency and optimizing performance.

1

Enter File Path

In the Path field, type the exact file path or full URL of the content you want to prefetch. Prefetch currently supports single-file operations only.

Examples:

/videos/launch.mp4
https://origin.example.com/assets/banner.jpg

Each Prefetch request must target one file path. Wildcard or directory-level prefetching is not supported.

2

Execute the Prefetch

Click Prefetch File to start the caching process. Medianova CDN will send a controlled HTTP GET request to your origin and store the retrieved file in the nearest edge or shield cache layer.

Once completed, the file will be ready for instant delivery to end users on first request.

Medianova’s Prefetch mechanism performs controlled fetch operations that proactively warm up cache layers. This eliminates the delay caused by a first-time cache miss and reduces origin load during peak demand.

Monitor Prefetch Requests

All Prefetch operations are listed in the Prefetch Log table below. Use this view to track the status and results of your Prefetch actions.
