Frequently Asked Questions
Do you support cache warming or preloading content onto the CDN?
To ensure fair cache management and file distribution, we do not currently allow preloading files into cache.
We hae a ‘Smart Preloader’ feature on Optimizer that monitors dynamic HTML requests going through bunny.net. If the system detects a request is slow, and might be negatively impacting the user experience, it will respond to the user with a special preloader screen HTML response. More details can be found here: https://docs.bunny.net/cdn/performance/smart-preloader
