Instructs edge servers to retrieve content linked from requested pages as they load, rather than waiting for separate requests for the linked content. This behavior applies depending on the rule's set of matching conditions. Use in conjunction with the prefetchable behavior, which specifies the set of objects to prefetch.

Note that prefetch is disabled in Ion and Dynamic Site Accelerator by default. To enable the behavior, you need to activate it in your property.
