As per the javadocs, sendRedirect can also take a relative path, but the
container has to convert it to an absolute URL before sending it to the
server.

It refers to the HTTP response code 307.
It is different from the moved Permanently (HTTP response code 301). For
details see RFC2616 available from http://www.rfc-editor.org/

requestDispatcher.forward() is used to pass the request from one servlet/jsp
to another servlet/jsp for processing (Servlet Chaining). The User-Agent is
not aware of this, and sees only one request and a response to it. This is a
totally server side concept.
In the case of sendRedirect() the server sends a response to the User-Agent
telling it that the resource requested is now available at the mentioned
URL. The User-Agent issues another request to the indicated URL. Hence this
results in two requests and two responses.
