Extend Count1.jsp (copying and renaming it as Count2.jsp?) so that the
application object is used to display the total number of times that the page has
been visited by anybody (in all sessions). If you use a name for the JSP that is
different from the one used in the previous question, remember to modify the
initial HTML page (copying and renaming it?) so that pressing the button takes
the user back to the correct JSP. When testing this program, open up two
browser windows and observe the difference between the two counts in each
pair and the difference between the contents of the two windows.
