3xxDetailed Explanation
HTTP 308 Permanent Redirect indicates that a resource has permanently moved to a new URL while preserving the HTTP method. Like 301, but unlike 301, it does not allow clients to change the method (e.g., POST stays POST). It is the preferred choice when permanently renaming API endpoints to avoid breaking POST or PUT clients.
Common Causes
- ▸An API endpoint is permanently renamed and POST method must be preserved
- ▸A domain change requires permanent redirect while keeping method intact
- ▸URL restructuring where PUT/DELETE requests need permanent redirect
- ▸Microservice migration routing old paths to new service permanently
How to Fix
- 1.308 is normal behavior — update clients to use the new URL
- 2.From an SEO perspective, PageRank is passed exactly like 301
- 3.For GET-only resources, 301 is acceptable
- 4.Verify the Location header contains the correct new URL
