203 Non-Authoritative Information
A proxy modified the successful response.
What it means
The payload came from a transforming proxy rather than directly from the origin server.
What your client should do
Treat it like 200, but know the body may differ from what the origin sent.
Should you retry?
No. Repeating the same request will give the same result.
