HTTP status codes / 3xx — Redirection
308 Permanent Redirect
Permanent redirect that preserves the method and body.
What it means
The method-preserving sibling of 301. The resource moved for good and the original method must be kept — important for APIs that move POST endpoints.
Common causes
- Permanent move of a POST/PUT endpoint
- API version migrations done right
Reproduce it in cURL
curl -i https://httpbin.org/status/308
Same request, no terminal: paste this into the cURL converter for native code, or straight into ReqPad on your phone.
How to debug it
Old HTTP clients occasionally do not support 308; if a redirect mysteriously fails only in one stack, check its 308 handling.
Server-side note: Ancient HTTP clients may not implement 308 — if one stack fails on it, that is why.
The fastest way to pin down a 308 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.
