sendRedirect is not limited to jsp or html. sendRedirect means you are creating new request to get something from server. so it can also be request for servlet
Moreover, sendRedirect is not limited by the application or even web-container's boundaries, because it actually forces the client (browser) execute this redirect. So you can specify the whatever URL you want. For example:
SCJP 6.0(95%), SCWCD 5(94%), SCJD (working on B&S v.2.3.1)
