推荐答案

在用户表中添加了两个字段，分别为状态和IP地址

每当用户登录时，我的意思是会话同时将更改状态创建为联机"，并跟踪ipaddress以进行功能响应.

同时用户注销后将状态更改为Offline

因此，这里您得到了逻辑，就像status=Offline授予登录权限

否则if status==Online，您可以限制登录不同位置的权限.

in User table add two more field as a Status and IPAddress

when ever user login i mean session create change status to Online at the same time track ipaddress for feature response.

at the same time when ever user logout change status to Offline

so, here u got logic as if status=Offline give permission to login

else if status==Online you can restrict the permission to login different locations.

inherit ICallbackEventHandler this eventhandler it ca automatically create two methods one is return results another one is store the values and close the i mean kill the sessions.

public partial class 

//
this event handler is catch the browser information whn browser naviage or close it can handle.

public partial class sample : System.Web.UI.Page, ICallbackEventHandler
{
 protected void Page_Load(object sender, EventArgs e)
    {
      ClientScriptManager cm = Page.ClientScript;
            String cbReference = cm.GetCallbackEventReference(this, "arg", "ReceiveServerData", "");
            String callbackScript = "function CallServer(arg, context) {" + cbReference + "; }";
            cm.RegisterClientScriptBlock(this.GetType(), "CallServer", callbackScript, true);
    }
public string GetCallbackResult()
    {
        return "Success";
    }
 public void RaiseCallbackEvent(string eventArgument)
    {
       //here kill the sessions
    }

}

before writing this you can take .js file
write like this and refere all .aspx pages
function confirmExit() {
//do something
}
function ReceiveServerData(arg, context) {

}
