@Steven: any tips? Is there any spec for the headers?
Any pointers to existing code?

Thanks!

There's an Intent to Ship for this on blink-dev:

If there's any feedback on this from Gecko developers, it would be much appreciated.

This is actually unrelated to that intent.  This bug is about exposing the information in devtools, not about having it available to script APIs.  I'm not aware offhand of a bug about exposing it to script APIs.

I don't believe anyone has looked at the proposed spec API yet to have feedback on it.

Note that since Server-Timing is an HTTP *trailer* (at end of the payload instead of the beginning), it will need some special support from necko.  I've filed bug 1413999 for that.

It does look like bug 1403051 is a dupe of this one?  If not, perhaps it's the one that needs to depend on bug 1413999?

Yes, let's close this one.
