A web application uses the HttpSession mechanism to determine if a user is "logged in." When a usersupplies a valid user name and password， an HttpSession is created for that user. The user has access tothe application for only 15 minutes after logging in. The code must determine how long the user has beenlogged in， and if this time is greater than 15 minutes， must destroy the HttpSession.
Which method in HttpSession is used to accomplish this？（）
A.Getcreationtime
B.Invalidateafter
C.Getlastaccessedtime
D.Getmaxinactiveinterval

Your IT department is building a lightweight Front Controller servlet that invokes an application logic objectwith the interface：public interface ApplicationController {public String invoke（HttpServletRequest request）}The return value of this method indicates a symbolic name of the next view. From this name， the FrontController servlet looks up the JSP URL in a configuration table. This URL might be an absolute path or apath relative to the current request. Next， the Front Controller servlet must send the request to this JSP togenerate the view. Assume that the servlet variable request is assigned the current HttpServletRequestobject and the variable context is assigned the webapp’s ServletContext.Which code snippet of the FrontController servlet accomplishes this goal？（）
Which ensures that a JSP response is of type "text/plain"？（）
