Hi all,
The WebPerf WG is preparing to move the Resource Timing Level 2 spec to
CR,
https://www.w3.org/TR/performance-timeline-2/
This spec defines a PerformanceResourceTiming interface, which
participates in the Performance Timeline and facilitates timing
measurement of downloadable resources. The information exposed by this
interface is defined by a set of attributes[1] in the
PerformanceResourceTiming interface.
For Cross-origin Resources, the spec defines a Timing-Allow-Origin
Response Header[2] and a timing allow check algorithm to determine
whether their information can be fully exposed. Please also look at the
Privacy and Security section[3] for more detail.
Please let us know if there is any security concern for Performance
Timeline before the end of January, either by email
<public-web-perf@w3.org> or use GitHub issues
<https://github.com/w3c/resource-timing>.
Thanks.
