The difference between the forwarding and redirection of website skills-Website Application

REDIRECT process : client browser sends HTTP request----The Web server accepts and sends a 302 response requiring the client browser to send a new HTTP request----The client browser accepts this response and sends a new HTTP request to the server---- The server seeks resources from this request and sends it to the customer, which can redirect to any URL and cannot share data in the request scope.

forwarding Process : The client browser sends an HTTP request----The Web server calls an internal method to complete the request processing and forwarding action within the container after accepting the request----to send the target resource to the customer, which can only be used in the same Web application. You can share data in the request scope.

How do you choose to redirect or forward? Forwarding is usually faster and can keep objects within the request, so he is the first choice. However, since the URL in the browser still points to the start page after forwarding, the start page will be called back if the current page is overloaded. If you do not want to see such a situation, select redirect.
