How to Prefetch

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

Prefetch allows you to pull specific files from your origin into the CDN cache before any user requests them. Use this feature to eliminate cache misses, reduce origin load, and ensure fast delivery to the first users.

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

Prefetch does not overwrite existing cached content. To update a file that is already cached, you must first Purge it and then Prefetch.

Prefetch via Control Panel

1

Enter File Path

In the Path field, enter one file path per line. Each line must point to a specific file you want to prefetch.

Examples:

/videos/product_launch.mp4  
/assets/images/banner.jpg  
/css/style.css

Wildcard paths (e.g. /images/*) are not supported.

2

Execute the Prefetch

Click Prefetch Files to initiate the operation. Medianova will send an HTTP GET request to your origin for each file and cache the response.

Once complete, those files will be ready for instant delivery from the CDN cache.

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.
