3xx Redirection Status Codes

3xx Redirection Status Codes indicate that the requested resource has been moved to a different location, and the client should take further action to complete the request. They are essential for guiding users and search engines to the correct resources.

Redirection: A technique used in web development that sends users and search engines to a different URL than the one they initially requested.
