Subject: [pdm-devel] [PATCH proxmox v3 05/21] auth-api: check for new prefixed cookies as well
Date: Thu, 27 Feb 2025 15:06:56 +0100 [thread overview]
Message-ID: <20250227140712.209679-6-s.sterz@proxmox.com> (raw)
In-Reply-To: <20250227140712.209679-1-s.sterz@proxmox.com>
this makes sure that newly generated cookies that are prefixed with,
for example, `__Host-`, for security purposes, are correctly picked
up on. otherwise, the new cookies would not be able to yield proper
authentication.
currently this still falls back to insecure non-prefixed cookies. we
should deprecate them in the long-term and remove this fallback.
