HTTP 307 Redirect

HTTP 307 is a status code that indicates a temporary redirect, where the client should repeat the original request using the same HTTP method (e.g., GET, POST) to a new URL provided in the response. It is part of the HTTP/1.1 specification and ensures that the request method and body are preserved during the redirection, unlike some other redirect codes. This makes it particularly useful for maintaining the integrity of non-idempotent requests, such as POST operations, during temporary server-side changes.

Also known as: 307 Redirect, HTTP 307, Temporary Redirect, 307 Status Code, HTTP/1.1 307

Why learn HTTP 307 Redirect?

Developers should use HTTP 307 when they need to temporarily redirect a client to a different URL while preserving the original request method and data, such as during server maintenance, load balancing, or A/B testing scenarios. It is essential for handling non-idempotent requests safely, as it prevents unintended side effects that could occur with methods like GET redirects. For example, in a web application, if a POST request to submit a form needs to be redirected to a backup server, HTTP 307 ensures the form data is not lost or altered.
