Flexible syntax for defining what outgoing links are eligible to be prepared speculatively before navigation. Enables access to additional enhancements, such as use of a private prefetch proxy, where applicable.

Motivation

Enable additional avenues of development for pre-navigation speculation, including requiring the anonymization of the client IP address and heuristics to identify the best outbound links to prefetch. The platform and browser should help developers make the best use of these capabilities to accelerate navigation between pages.
