hi, you should not create new proxy object on every button click, you should persis it during postback to retain session like below

protected void Button1_Click(object sender, EventArgs e)
	{
		ServiceReference1.Service1SoapClient o;
		if(Session["Proxy"] == null)
		{
			o = new Service1SoapClient();
			o.CookieContainer = new CookieContainer();
			Session["Proxy"] = o;
		}
		else
			o = Session["Proxy"] as ServiceReference1.Service1SoapClient;
		int k = o.IncSessionCounter();
	}
