<div>I think there’s interest.  The tricky part would be getting access to the HTTP trailers with NSURLSession, libsoup, and if there’s interest libcurl.  I can help out with the NSURLSession implementation if someone else gets it working with libsoup.<br class="">

The Server Timing API reads response headers and appends metrics to the timing entry associated with the request/response cycle (either the PerformanceNavigationTiming or PerformanceResourceTiming entry). This allows applications and analytics vendors to collect
