我正在做关于开发网站的项目。我是 ASP.net 的新手，现在我有一个关于登录会话的问题，当用户登录时，同时在网上冲浪的每个人也会被记录为用户无论他们是否登录。只有当有人单击注销按钮并且每个人都注销时，会话才会结束。请帮我。每一个帮助将不胜感激。这是我的代码，我在我的母版页中编写了这些代码：
protected void Page_Load(object sender, EventArgs e)
{
string equip = "Equipment.aspx";
string url = HttpContext.Current.Request.Url.AbsoluteUri;
if (url.IndexOf(equip) != -1) { Calendar2.Visible = false; Image1.Visible = false; }
equip = "Bookings.aspx";
if (url.IndexOf(equip) != -1) { Calendar2.Visible = false; Image1.Visible = false; }
equip = "Rooms.aspx";
if (url.IndexOf(equip) != -1) { Calendar2.Visible = false; Image1.Visible = false; }
equip = "Users.aspx";
if (url.IndexOf(equip) != -1) { Calendar2.Visible = false; Image1.Visible = false; }
if (!Page.IsPostBack)
{
if (user != "" && user != null)
{
loginStatus = true;
redirectpage = false;
}
else
{
redirectpage = false;
loginStatus = false;
user = "";
authority = 0;
}
}
else
{
if (user == "" || user==null)
{
if (cal != null)
{
}
loginStatus = false;
authority = 0;
}
else
{
if (cal != null)
{
}
loginStatus = true;
}
}
}

{
SqlConnection oConn =
new SqlConnection();
oConn.ConnectionString = @"Data Source=STAVROS\SQLEXPRESS;User ID=sa;Password=123abc;Initial Catalog=webdev";
sSQL = "select * from tbl_user where username = '" + Login.UserName + "'AND password = '" + Login.Password + "' ";
SqlCommand oComm1 = new SqlCommand(sSQL, oConn);
try
{
oConn.Open();
SqlDataReader i = oComm1.ExecuteReader();
if (i.HasRows)
{
while (i.Read())
{
user = i.GetString(0);
authority = i.GetInt16(7);

string p = "Home.aspx";
if (url.IndexOf(p) != -1) { Response.Redirect("Home.aspx"); }
Helper.CreateUserSession(Session, user);
}
}

{

}
i.Close();
}

}
