User Control User Login judgment

Using the user control Whelogined.ascx, the code is as follows:
Namespace HEZjs.WebForm.modules.ascx
{
Using System;
Using System.Data;
Using System.Drawing;
Using System.Web;
Using System.Web.UI.WebControls;
Using System.Web.UI.HtmlControls;

{
Place user code here to initialize page
String strpath = HEZjs.WebForm.wfFunction.SiteUrl (this. Parent.page) + "modules/aspx/modlogin.aspx";
if (this. session["to page"] = = null)
This. Session.add ("Transfer to Page", this.) PARENT.PAGE.REQUEST.RAWURL);
Else
This. session["Transfer to Page" = this. PARENT.PAGE.REQUEST.RAWURL;
if (this. session["user"]!= null)
{
if ((HEZjs.Sys.sysUser) this. session["User"]). logined)
{

Strpath is used to specify the system login interface and the HEZJS.WEBFORM.WFFUNCTION.SITEURL () method is used to return the web address
Session[the address of the page to which the user requests to be placed in the "to page"]
session["User" contains a HEZjs.Sys.sysUser object that includes a logined member to return whether the user is logged in
Drag the user control directly to each page that needs to be logged on, and when the user requests the page, if the user is not logged in, it will go to the login page and, if it is already logged in, normal browsing.
Is it convenient?
You can also make a user's decision about the permissions of the requesting page and the general style of the specified page (if no style is specified beforehand) where the code is labeled.
