What's the difference between forward and sendredirect?

Know different but can't say clearly

Forward is the forwarding request, which is processed internally by the server.The address displayed on the page is still the address originally requested.

sendRedirect sets the 302 header and then sends it to the browser.After the browser receives the 302 request, it sends a request to the redirected page again.

It seems that one is to save user information, and the other is not to save user information~~

forward is forwarding and can carry data

sendRedirect is a redirect, a bit like a super link in html

But use sendRedirect in Servlet to transfer the request to javabean

In addition, forword can only request forwarding in the current site.

And sendReddrect can jump to any URL
