HTTP 308 Permanent Redirect
Permanent version of 307. Method is preserved across the redirect, link equity transfers.
What it means
308 is the strict, modern equivalent of 301: permanent redirect that explicitly preserves the request method and body. Most use-cases for 301 should arguably use 308 in 2025+ codebases, but 301 remains universally supported and SEO tools handle it well.
Use 308 specifically when you have non-GET traffic that needs to follow the redirect and you need the move to count as permanent for caching and indexing.
Common causes
- Permanent API endpoint relocation (e.g. /v1/users → /v2/users)
- Modern framework default for permanent moves
- HTTPS enforcement that needs to preserve POST bodies
How to fix it
- 1Update API clients to use the new URL directly
- 2Confirm caching layers honor the permanent move
