The browser sends back an HTTP 302 code, which means that the requested resource has temporarily moved to a different location. Along with the HTTP 302 code, the server sends back the new location of the item.
The 302 status code A response with 302 is a common way of performing URL redirection. Along with the 302 status code, the response should include a Location header with a different URI.
