1472240 - Network monitor will show 425 even if the http transaction is restarted and succeeded.

Status: NEW

(DevTools :: Netmonitor, enhancement, P3)

Description

[Dragana Damjanovic [:dragana]]

Code "425 Too Early" is received when we send data in the TLS1.3 early-data, but for the server it is to early and it wants us to repeat the request.
So we will repeat the http transaction and get a proper response. The devtool will still show 425 instead of 200 or 101...

This is reproducible for example:
https://cocalc.com/app#settings?session=default (only once bug 1453204 lands)

Thanks for the report!

Can you please provide detailed STR?
What exactly should I do after loading https://cocalc.com/app#settings?session=default ?

TLS 1.3 must be turned on security.tls.version.max set to 4 (this is default on Nightly)
open devtools (network tab)
load https://cocalc.com/app#settings?session=default
you will see a 425 response

if you do not see 425 response do following:
in upper right corner there is a "wifi" sign. Click on it, a dialog will show up, then click on "Reconnect". In devtolls there should be a 425.

425 is code when we send request to early. necko will repeat request and get 101. I think devtool should show 101 instead 425.
