sendRedirect(URL) sends a header back to the browser that tells it load from a new page
the URL. Therefore the original request and response is lost to the next page URL.
Where the request dispatcher insteads invokes the new page directly and if it is
a servlet passes the request and response objects onwards. The browser never
knows what there was a transfer from one servlet to another.
Caveat: Request dispatch only works on inside one web application.
That is
localhost:8080/app1/servlet/ThisServlet
cannot request dispatch to
localhost:8080/app2/servlet/AnotherServlet
So if you want to do that between web applications (and different machines)
you have to use `request.sendRedirect(URL)'.

Subject: Re: fordward servlets
Although this will work just fine, it is less elegant than Robert's solution
of "RequestDispatcher.forward(request,response)".
I have always used "response.sendRedirect(URL)" when some sort of error
occurs within the currently executing Servlet.
Can anyone shed some more light on this topic? Do we even have access to
'req' and 'res' the objects with "sendRedirect(URL)" or are they out of
scope? Suppose I'll test it.
