HTTP 308 Permanent Redirect

The resource has permanently moved and the request method must not change.

What 308 means

HTTP 308 Permanent Redirect is the strict version of 301. Like 307, it preserves the HTTP method during redirect. A POST request receiving a 308 must POST to the new URL. This is the correct code for permanent API endpoint moves.

Common causes

• Permanent API endpoint migration
• URL scheme change requiring method preservation
• Domain migration for API services

How to fix it

• Ensure all clients support 308 (older clients may not)
• Update API documentation with new endpoints

SEO impact

Passes link equity like 301. Use when you need permanent redirect with method preservation.
