Commonly assumed
A signed cookie remains valid when copied to any cookie name whose name-plus-salt text matches the original pair, and enabling legacy compatibility is a silent permanent fix.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- RequestFactory and Client execute without a server or database, keep POST form data separate from repeated query_params, let per-call query_params replace constructor defaults, and negotiate the Accept header.
- HttpResponse.set_signed_cookie and HttpRequest.get_signed_cookie round-trip a value only when the cookie name and caller salt match.
- Django 6.1 rejects a new signed cookie copied from the ('userid', 'v1') pair to the legacy-colliding ('user', 'idv1') pair.
- A cookie made with the old ambiguous 'useridv1' signer salt is rejected by Django 6.1's default settings.
- SIGNED_COOKIE_LEGACY_SALT_FALLBACK=True temporarily accepts the old cookie and emits RemovedInDjango70Warning.
