All HTTP status codes

HTTP 300 Multiple Choices

Redirection

More than one representation of the resource exists and the client should pick one. Rarely used — most servers pick a representation themselves.

Defined in RFC 9110

Common causes

  • Content negotiation endpoints listing alternates

How to fix it

  1. Prefer responding with a concrete representation plus a Vary header instead

Related status codes

301 Moved Permanently

The resource has permanently moved to the URL in the Location header. Browsers cache it and search engines transfer ranking signals to the new URL.

406 Not Acceptable

The server can't produce a response matching the client's Accept headers (content type, language, encoding).
