Expose RTT information in Workers for QUIC

When using Cloudflare workers over HTTP/1 or 2, the TCP RTT information was exposed in Cloudflare workers through the request.cf.clientTcpRtt field, which I used to forward to my own server in order to estimate the responsiveness of my website.

However, when using HTTP/3, the field is currently unavailable.

Since QUIC also has the same underlying concepts of congestion control and uses RTT related metrics, I would like to have the same information exposed when using HTTP/3.


Would appreciate that as well. :+1:

Consider voting for the feature in that case :slight_smile:

While it’s a niche feature, a few votes might help this request to be noticed.
