11:07 Doug: NEL and Reporting moved from WICG to WebPerf | |
11:07 ... we have i2s LGTM's for both in Chrome | |
11:07 ... we'll be launching as stable experiments this quarter | |
11:07 ... we should have live implementation in chrome by EOQ | |
11:08 ... some good feedback from i2s process, which resulted in spec updates | |
11:08 ... one common question from TAG was about using JSON in headers | |
11:09 ... we got some pushback from TAG on JSON; there are known gotchas with JSON — e.g. numbers. | |
11:09 ... alternative would be to use structured headers (being developed by httpwg / IETF) | |
11:10 ... after some analysis, we ended *not* doing that and sticking with JSON |

Navigation and Resource Timing provides timing data for the fetch, but currently there is no interoperable way for the server to communicate own timing information to the client. For example:
<!--Page generated in X.X seconds.-->
, and many sites provide more detailed stats (cache, db, generation) to enable performance debugging.Instead of relying on arbitrary HTML comments, we can define an HTTP header that can be used to send key-value pairs in a well defined format. Making this data available via a well defined interface would...
