VERSION: <jsp:include page="/InfoServlet?name=VERSION"></jsp:include>
this will cause a call to the InfoServlet with the parameter name and the value VERSION. The output will be written by the InfoServlet.
The calling servlet has to use the same access method to the response as the jsp and should not close the stream. Otherwise the output of your jsp will stop immediately.
So if you don't know just use response.getOutputStream() to write to the response.
