Pagemethods in JQuery

[vuyiswamb]

Good Day All

I have a web Method defined like this

[System.Web.Services.WebMethod]
		public static bool CheckSessionExpiration()
		{
			System.Web.HttpContext.Current.Session["CurrentLoginUser"] = null; //This is for Testing Purpose


			if (UserSecurity.GetLoggedInUser() == null)
			{
				return false;
			}
			else
			{
				return true;
			}
 
			 
		}

and in Jquery i have a function that calls this

function ProcessAction() {

PageMethods.CheckSessionExpiration(OnCheckSessionExpirationComplete, OnCallError);

    if (IsLogin == true) {
        alert("Inside the Function");
        var txtNote = $("[id$=txtNote]").val();
        var txtIdentNo = $("[id$=txtIdentNo]").val();
        var sIdentNo = "";

        DisableControls();
        CleanIdentNoList();
        if (ValidFields()) {
            //Get Subscriber Detail
            gAction = $("[id$=cmbAction]").val();
            gNote = txtNote;
            sIdentNo = jQuery.trim(txtIdentNo);
            gMSISDNList = sIdentNo.split("\n");
            gMSISDNIndex = -1;

            ProcessNextItem();
        }
        else {
            EnableControls();
        }
    }
    else {
        window.location = "Login.aspx";
    }

}

and i have a Callback function defined like this

function OnCheckSessionExpirationComplete(result,methodName) {
    if (result == false) {
        
        IsLogin = false;
    }
    else {

        IsLogin = true;
    }

}

Now the "IsLogin" variable is a Global variable defined like this

var IsLogin = true;

What i want to do is to redirect the user if the Session is null, as you can see i have added the line

System.Web.HttpContext.Current.Session["CurrentLoginUser"] = null; //This is for Testing Purpose

For testing Purpose , but my problem is is that, even if its null, the

alert("Inside the Function");

is fired, what i am i doing wrong.

THanks
