3xx Redirection
Cacheable by default
308 Permanent Redirect
Same as 301, but the method and body must not be changed.
What causes it
- A permanent API endpoint move that must not turn POSTs into GETs.
How to fix it
- Like 301, this is cached aggressively. Confirm the destination is right before deploying.
