Depends on the HTTP server. If you use the previous code with Apache, I
think that Apache handled the redirect itself because it's not a legal
URL. Other HTTP servers don't do it usually and expect the client to handle
this kind of links.
HTTP spec says the Location header sent to a client should always be
a full URL.
BTW, the example code breaks the URL session handling that may be
configured on the servlet container.
The code should be:
response.sendRedirect(response.encodeRedirectURL(<whateverURL>));
