Why Do Browsers Not Automatically Re-submit POST Data After a Redirect?

The issue arises from security concerns. When the server sends a redirect to the browser, the browser will switch to sending a basic GET request instead of repeating the POST request. This is because the browser cannot decide for the user whether they would like to send the same data to the new URL as was intended for the original URL, especially when it comes to sensitive data like passwords and credit card numbers. It is not advisable to attempt to circumvent this issue; rather, it is recommended to use a registered path for the POST request or implement the other suggestions from the linked questions.
