What is the 308 Status Code in HTTP?

The HTTP 308 status code, known as “Permanent Redirect,” indicates that the requested resource has been permanently moved to a new URL. Unlike the 301 status code, which also denotes a permanent redirection, the 308 status code ensures that the original HTTP method remains unchanged during the redirection.

For instance, if a client sends a POST request to a URL and receives a 308 response, the redirection will occur while retaining the POST method.

What Causes the 308 Status Code?

The 308 status code is triggered in situations such as:

1. Permanent Resource Relocation: The resource has been permanently moved to a new location, and the client is expected to use the new URL for future requests.
2. URL Structure Changes: Websites update their URL structure to improve SEO or user experience and implement a 308 redirect to guide clients.
3. Server Configuration: Servers enforce permanent redirections for certain resources to ensure consistent access.
4. API Endpoint Updates: APIs use the 308 status code to inform clients of permanently updated endpoints.

Example of the 308 Status Code in Action

Imagine a scenario where a user attempts to access https://example.com/old-page. The server responds with a 308 status code, redirecting the client to https://example.com/new-page. The client updates its records and uses the new URL for subsequent requests, ensuring a seamless transition.

Unlike temporary redirects, this redirection is permanent, and the client should avoid requesting the old URL in the future.

How to Fix or Manage the 308 Status Code

Managing the 308 status code effectively ensures smooth redirections and user experience. Here are some best practices:

1. Specify Correct Redirect Targets:
   
   • Use the Location header to indicate the new permanent URL accurately.
2. Configure Permanent Redirects:
   

In Apache servers, configure .htaccess files to implement 308 redirects:
Redirect 308 /old-path https://example.com/new-path

3. Preserve HTTP Methods:
   
   • Ensure that the server retains the original HTTP method during redirection.
4. Test Redirections:
   
   • Use tools like Postman or cURL to validate the redirection behaviour and ensure it meets expectations.
5. Monitor Performance:
   
   • Regularly check for broken links or improper redirections using tools like Screaming Frog.

Use tools like Postman, cURL, or browser developer tools to inspect and validate redirection responses.

When should I use the 308 status code?

Use the 308 status code for permanent redirections where the original HTTP method must be retained, such as API endpoint changes or resource relocations.

By understanding and correctly implementing the 308 status code, you can ensure seamless and efficient permanent redirections, enhancing both user experience and website performance.
