www.geo.fr gets stuck in a redirect loop because it depends on cross-domain cookies

[efixler]

When navigating to https://www.geo.fr/environnement/comment-la-secheresse-a-fait-decoller-le-skateboard-dans-la-californie-des-annees-1970-217924 the request shows the following behavior:

Request:

Responds with a 302:

HTTP/2 302 
server: AkamaiGHost

The request that it then sends to the prismedia host contains a cookie:

GET /?redirectHost=https%3A%2F%2Fwww.geo.fr&redirectUri=%2fenvironnement%2fcomment-la-secheresse-a-fait-decoller-le-skateboard-dans-la-californie-des-annees-1970-217924 HTTP/1.1

Sec-Fetch-Site: cross-site

And that host responds like this:

HTTP/1.1 302 Moved Temporarily
Server: AkamaiGHost
Content-Length: 0
Location: https://www.geo.fr?authId=d6d6e70eb02ef36655fb141159f15f63&redirectUri=%2fenvironnement%2fcomment-la-secheresse-a-fait-decoller-le-skateboard-dans-la-californie-des-annees-1970-217924
Date: Wed, 03 Jan 2024 15:02:02 GMT
Connection: keep-alive
Access-Control-Allow-Methods: GET, POST, OPTIONS
Access-Control-Allow-Origin: *

The authId is subsequently used for more 302s at www.geo.fr.

Question here is if there's a generalizeable behavior that tells us to copy cookies across crossdomain requests.
