forward和sendRedirect之间的区别

Question

I have come across these two statements on an interview question on the web:

 1.forward causes object stored in request as attributes to be lost;
 2.sendRedirect causes object stored in request as attributes to be lost;

I am now confident that the first statement is wrong since using request is definitely how forward works to pass values, but I am confused about the sendRedirect one, is it correct in this sense? Could experts help? Thanks.

Answer 1

与在服务器端发生的forward不同， sendRedirect导致浏览器向重定向位置发起新请求，这意味着第二个语句为真。
