The POST method sends data. It is more secure than the GET method.
For example, when you fill out a form on a website and click a submit button, your browser sends a POST request to the server.
The server then processes the information russia phone number example you submitted (such as your name and email address).
When you specify a 308 Permanent Redirect, you prohibit the browser from changing the HTTPS request method.
In other words, if the client made the original request using the POST method, the browser should continue to use the POST method when following the redirect.
Maintaining a POST request method is important if you want to secure and safeguard data, such as login credentials. Or if you want to save data, such as order information.
