HTTP status codes / 3xx — Redirection
Redirect that explicitly tells the client to GET another URL.
The "your POST was processed, now GET the result over there" redirect — the backbone of the POST→redirect→GET pattern that prevents duplicate form submissions. The follow-up request is always a GET.
curl -i -X POST https://httpbin.org/status/303
Same request, no terminal: paste this into the cURL converter for native code, or straight into ReqPad on your phone.
Expected after form-style POSTs; the redirect target should be fetched with GET regardless of the original method.
The fastest way to pin down a 303 is to reproduce the exact request and inspect what actually went over the wire — status, headers, timing and body, without your app code in the way. That is what an API client is for; ReqPad does it from your phone, with every request saved to history.
300 Multiple Choices · 301 Moved Permanently · 302 Found · 304 Not Modified · 307 Temporary Redirect · 308 Permanent Redirect — or the full reference.
