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.

?Hi,

I'd like to add support for Server Timing and wanted to gauge interest for supporting the feature.

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 and report the timing associated with any segment of the request/response cycle, in order to optimize application delivery.
