            PageMethods.PokeServerPage();
        }
        
        </script>



Step 5.

 [WebMethod(EnableSession = true)]
    public static void PokeServerPage()
    {
        //=> Poke server page to keep session alive...
    }


Step 6.
Security considerations...
                        

                            step 1. Firstly create facebook app you will need the app id and app secret and setup website URL, domain etc...

step 2. create this class in App_Code folder:

using System.Configuration;
using System.Web;

public class fbConnect
{
    public fbConnect()
    {

    }

    public static bool isConnected()
    {
        return (SessionKey != null && UserID != -1);
    }

    public static string ApiKey
    {
        get
        {
            return ConfigurationManager.AppSettings["APIKey"];
        }
    }

    public static string SecretKey
    {
        get
        {
            return ConfigurationManager.AppSettings["Secret"];
        }
    }

    public static string SessionKey
    {
        get
        {
            return GetFacebookCookie("session_key");
        }
    }

    public static int UserID
    {
        get
        {
            int userID = -1;
            int.TryParse(GetFacebookCookie("user"), out userID);
            return userID;
        }
    }

    private static string GetFacebookCookie(string cookieName)
    {
        string retString = null;
        string fullCookie = ApiKey + "_" + cookieName;

        if (HttpContext.Current.Request.Cookies[fullCookie] != null)
            retString = HttpContext.Current.Request.Cookies[fullCookie].Value;

        return retString;
    }
}


step 3. Create Default.aspx or Index.aspx on client side insert:
<!--
<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Facebook Integration Sample</title>
    <script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php"
        type="text/javascript"></script>    
</head>
<body>
    <form id="form1" runat="server">
        <div id="login">
            facebook test application <br />
            <asp:Panel ID="pnlLogin" runat="server">
                <fb:login-button length="long" v="2" onlogin="window.location.reload()">Login with facebook</fb:login-button><br />
             </asp:Panel><br />
            <asp:label id="lblMessage" runat="server" text="Not authenticated. Click Button to authenticate"></asp:label>
            <br /><br />
            <asp:Image ID="imgPic" runat="server" AlternateText="" Visible="false"/>
        </div>    
    </form>

    <script type="text/javascript">
        FB.init("appID", "fb_receiver.htm");
    </script>
</body>
</html>
-->

Step 4. In Default.aspx.cs insert:

using System;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using facebook;
using facebook.web;

public partial class _Default : System.Web.UI.Page 
{

    protected void Page_Load(object sender, EventArgs e)
    {
        if (fbConnect.isConnected()) // Check if this application is authenticated
        {           

                API api = new API();

                api.ApplicationKey = fbConnect.ApiKey;
                api.SessionKey = fbConnect.SessionKey;
                api.Secret = fbConnect.SecretKey;
                api.uid = fbConnect.UserID;

                // hide the facebook button
                pnlLogin.Visible = false;

            try // be careful using try catch because we always want to find the error...
            {
                //Get the data of the signed user.
                string fullName = api.users.getInfo().first_name.ToUpper() + " " + api.users.getInfo().last_name.ToUpper();
                lblMessage.Text = "You are login as " + fullName + " ID: " + api.users.getInfo().uid;
                imgPic.ImageUrl = api.users.getInfo().pic_big;

                Response.Redirect("Menu.aspx");
            }
            catch { pnlLogin.Visible = true; }
            
        }
        else
        {
            pnlLogin.Visible = true;
        }
        
    }
}

Step 5. Then you need to add Cross Domain Site:
<!--
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Cross-Domain Receiver Page</title>
</head>
<body>
<script src="http://static.ak.facebook.com/js/api_lib/v0.4/XdCommReceiver.debug.js" type="text/javascript"></script> 
</body>
</html>
-->
Step 6. This is the last step here you need to add appID, appSecret and callbackUrl in web.config

</configSections>
	<appSettings>
    <add key="APIKey" value="appID"/>
    <add key="Secret" value="appSecret"/>
    <add key="Callback" value="http://simpa.dk/FacebookLogin/"></add>
	</appSettings >
	<connectionStrings>


Download the binaries here "http://simpa.dk/FacebookLogin/bin.zip"

Happy Coding...!
                        

                            step 1. Firstly create facebook app you will need the app id and app secret and setup website URL, domain etc...

step 2. create this class in App_Code folder:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Configuration;
using System.Web;


public class ConnectAuthentication
{
    public ConnectAuthentication()
    {

    }

    public static bool isConnected()
    {
        return (SessionKey != null && UserID != -1);
    }

    public static string ApiKey
    {
        get
        {
            return ConfigurationManager.AppSettings["APIKey"];
        }
    }

    public static string SecretKey
    {
        get
        {
            return ConfigurationManager.AppSettings["Secret"];
        }
    }

    public static string SessionKey
    {
        get
        {
            return GetFacebookCookie("session_key");
        }
    }

    public static int UserID
    {
        get
        {
            int userID = -1;
            int.TryParse(GetFacebookCookie("user"), out userID);
            return userID;
        }
    }

    private static string GetFacebookCookie(string cookieName)
    {
        string retString = null;
        string fullCookie = ApiKey + "_" + cookieName;

        if (HttpContext.Current.Request.Cookies[fullCookie] != null)
            retString = HttpContext.Current.Request.Cookies[fullCookie].Value;

        return retString;
    }
}


step 3. Create Default.aspx or Index.aspx on client side insert:

Step 5. Then you need to add Cross Domain Site:

        type="text/javascript"></script>
</body>
</html>
-->

Step 6. This is the last step here you need to add appID, appSecret and callbackUrl in web.config

<configuration>
  <appSettings>
  <add key="APIKey" value="appID"/>
  <add key="Secret" value="appSecret"/>

  </appSettings>
  <connectionStrings>
