csdn 登陆之后他会回到原来那个资源页面

<%@page import="com.gdf.bean.Member"%>
<%
Member user=(Member)com.gdf.util.SessionManager.getUser(request);
String location=request.getRequestURI();
if (request.getQueryString()!=null)
{
location="?"+request.getQueryString();
}
if(user==null){
out.print("<script>window.open('/userLogin.jsp?location="+location+"','_parent')</script>");
return;
}
%>

 

然后在登录页面中用request.getParameter("location")获取访问的地址。
