                  cookie.setMaxAge(-1);

how i remove cookie?

I worked on JSP & JAVA, this is the source code of JSP file.

 

Why are you making another object, don't you need to use the same object?

 Cookie cookie= new Cookie("iAdminName",iAdminName);
                  cookie.setMaxAge(-1);
                  response.addCookie(cookie);

cookie.setValue(null);
cookie.setMaxAge(0);
cookie.setPath("/");

My psychic powers tell me...

...your original cookie has a different path.

I suspect he kills the cookie on a different page.

 

yea lolz as CDarklock said u saving cookie in diffrent path and deleteing cookie of diffrent path
try this :

 Cookie killMyCookie = new Cookie("iAdminName", null);
            killMyCookie.setMaxAge(-0);
            killMyCookie.setPath(request.getHeader("host"));
            response.addCookie(killMyCookie);
