3xx Redirection
The 307 (Temporary Redirect) status code is similar to 302 Found, but with a crucial difference: the user agent must not change the HTTP method of the original request. If the original request was POST, the redirect request must also be POST. This ensures that form data is not lost during a temporary redirect.
When a server needs to redirect a POST request temporarily to another endpoint for processing (e.g., during a blue-green deployment or maintenance window), use 307 Temporary Redirect. The client will re-POST the same data to the new URL without losing the request body.
// Laravel - temporary redirect preserving method
return redirect()
->away('https://backup.example.com/api/process')
->setStatusCode(307);
// This preserves POST/PUT/DELETE methods through the redirect
Mistake: Using 302 instead of 307 when POST data must be preserved
Fix: Most browsers change POST to GET when following 302. If you need to preserve the original HTTP method (especially POST), always use 307 Temporary Redirect.
Mistake: Using 307 for permanent redirects
Fix: If the redirect is permanent, use 308 Permanent Redirect instead of 307. 307 implies the original URL should be used for future requests.
