How is 307 different from 302?

307 guarantees the HTTP method is preserved. With 302, some clients may change POST to GET, but 307 never changes the method.

When should I use 307 vs 302?

Use 307 when it is critical that the HTTP method (especially POST) is preserved. Use 302 when you are fine with the method potentially changing to GET.

HTTP 307 Temporary Redirect — What It Means & How to Fix It

Warning3xx redirection

Overview

The HTTP 307 Temporary Redirect status code indicates the resource is temporarily at a different URL, and the client must use the same HTTP method for the redirect request.

Key Details

Unlike 302, this status code guarantees the HTTP method will not change during the redirect.
A POST request will remain a POST after following the redirect.
The client should continue using the original URL for future requests.
It was introduced in HTTP/1.1 to fix the ambiguity of 302 regarding method preservation.

Common Causes

A resource is temporarily available at a different location.
HTTPS enforcement redirecting HTTP to HTTPS while preserving the method.
Load balancing or failover directing traffic to a backup server.

Steps

1Follow the redirect to the URL in the Location header using the same HTTP method.
2Resend the original request body if applicable.
3Continue using the original URL for future requests.
4Verify the redirect preserves your intended HTTP method.
