JSP views cannot set any headers

[rtwruck]

When fulfilling GET requests with a JSP view, you'd expect to be able to use JSP features like <%@page contentType="text/html; charset=UTF-8" %> or setting headers like 'Expires'. Unfortunately though, JspViewResolver chose to invoke RequestDispatcher.include, where

"The included servlet cannot change the response status code or set headers; any attempt to make a change is ignored."

Is there any reason for not using RequestDispatcher.forward ?
