    When a JSP target the Servlet, How will you ensure that the response back from the servlet will target the JSP that invoked?

  2. Direct Servlet Response to the Calling JSP[ Go to top ]

    You can tell which JSP targeted a servlet (through a hyperlink or form submission) by looking the HTTP "referer" header:

    String refererURL = request.getHeader("referer");

    This will be the URL of the page that invoked the servlet.
