PrefetchCache

@Profile.ExperimentalUrlPrefetch
class PrefetchCache

PrefetchCache manages the configuration of the prefetch cache for a Profile.

It allows applications to tune the behavior of prefetch cache by setting limits such as the maximum number of prefetches and the time-to-live for prefetched responses. These configurations are applied to all WebViews associated with the profile.

Use getPrefetchCache to obtain the PrefetchCache instance for a specific profile.
