3xx Redirection
303 See Other
The result of the request is at another URL, which the client should fetch with GET.
What causes it
- The POST/Redirect/GET pattern that stops a browser refresh re-submitting a form.
How to fix it
- This is the correct status for "form submitted, now go look at the result" — not 302.
