TIL that React Native’s fetch implementation will sometimes persist cookies from server responses, but it’s not considered reliable. More importantly for me, if you don’t want to involve cookies at all in your requests, credentials:omit is also considered unreliable
I was working through a bug where a certain API endpoint was redirecting in a way that didn’t make any sense until I realized it was detecting stale cookies and treating the request as a partially authorized HTML request 🤦
