Specification

None

Summary

In performanceResourceTiming, expose the "initiator info". "Initiator info" is information on what other resource caused the fetch of the current resource. This information can be used to construct the dependency of the resources from RUM(real user monitoring) data. It helps web sites and CDN to optimize resource delivery speed. It helps security products to track rogue resources too.
