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. Learn more.
