HTTP 308 Permanent Redirect

🔄 What is HTTP 308 Permanent Redirect?

The HTTP 308 Permanent Redirect status code is part of the HTTP protocol indicating that the requested resource has been permanently moved to a different URI. This suggests that clients should update their requests to the new URI for future interactions.

🌟 Importance of HTTP 308 in SEO

HTTP 308 redirects are crucial for maintaining SEO rankings during URL changes. They ensure link equity transfer, letting search engines know about new URL locations, thus preventing SEO penalties due to broken links.

⚙️ How Does HTTP 308 Work?

1. A client makes a request to a URI that has been moved.
2. The server responds with a 308 status code and provides the new URI.
3. The client updates its records and uses the new URI for future requests.
4. The HTTP method and body remain unchanged, replicating the original request at the new URI.

📌 Examples of Implementing HTTP 308

• A website has permanently moved from /old-page to /new-page and uses HTTP 308 for redirection.
• An API endpoint changing its base URI while maintaining client functionality via HTTP 308.
