2266	QUIC: cookies not transferred correctly on redirect	mkg20001@…		"Occurs with Chrome 93.0.4577.82

Cookies are not properly transferred when accessing a site, which redirects to an SSO portal and then redirects back. (SSO being h2-enabled, application being h3-enabled)

The session cookie of the application is shown to be sent by chrome to the application, but the application did not receive it or something else occurred

The problem was resolved by switching to the nginx mainline version, meaning it seems to be a fault in either NGINX's or Chrome's QUIC implementation.

(Application was GitLab, SSO was Keycloak in case someone wants to reproduce)"	defect	closed	critical		nginx-core		duplicate	quic	mkg20001@…	Linux nix-test 5.10.52 #1-NixOS SMP Tue Jul 20 14:05:59 UTC 2021 x86_64 GNU/Linux	"nginx version: nginx/1.21.3
