  I'm currently working with a web service in which I want to keep track of individual sessions, i.e. for each user.
  
  The code that I have in my web service is as follows...
  
  public class Service : System.Web.Services.WebService
  {
      public Service()
      {
         
      }
     
       bool IsAuthenticated
          {
              get
              {
                  object state = Session["IsAuthenticated"];
                  if (state != null)
                  {
                      return (bool)state;
                  }
                 
                 
                  return false;
              }
              set
              {
                 
                  Session["IsAuthenticated"] = value;
              }
          }
          [WebMethod(EnableSession = true)]
          public bool LogIn(string userName, string password)
          {
              // UserManager userManager = new UserManager();
              bool authenticated;
              authenticated = Authenticate(userName, password);
              // userManager.Authenticate(userName, password);
              IsAuthenticated = authenticated;
              return authenticated;
          }
          [WebMethod(EnableSession = true)]
          public void LogOut()
          {
              IsAuthenticated = false;
          }
  
          [WebMethod(EnableSession = true)]
          public int Add(int num1, int num2)
          {
              if (IsAuthenticated == false)
              {
                  throw new UnauthorizedAccessException("Invalid user name or password provided");
              }
              return num1 + num2;
          }
          [WebMethod(EnableSession = true)]
          public bool Authenticate(string userName, string password)
          {
              if (userName == "Goyal" && password == "Goyal")
              {
                  return true;
              }
              else
              {
                  return false;
              }
          }
     
     
  }
  
  and aspx page code is as follow
  Security.Service obj;
              System.Net.CookieContainer container = new System.Net.CookieContainer();
             
      protected void Page_Load(object sender, EventArgs e)
      {
          obj = new Security.Service();
         
          obj.CookieContainer = new CookieContainer();
          Session["obj"] = obj;
  
      }
      protected void btnAdd_Click(object s, EventArgs e)
      {
  
          try
          {
              obj = (Security.Service)Session["obj"];
              bool test = obj.LogIn("Goyal", "Goyal");
              int sum = obj.Add(Convert.ToInt32(txtFirstNumber.Text), Convert.ToInt32(txtSecondNumber.Text));
              Response.Write(sum);
          }
          catch (Exception ex)
          {
              Response.Write(ex.ToString());
          }
      }
      protected void btnCancel_Click(object s, EventArgs e)
      {
  
      }
      protected void lnkLogOut_Click(object s, EventArgs e)
      {
          Security.Service obj = new Security.Service();
          obj.LogOut();
          lnkLogOut.Text = "Login";
           
      }
  
  
  It is working fine but it is only Issue that LOGIN FUNCTION AND ADD FUNCTION call at same
  time ...
             I donot want like this ...... I want call LOGIN function on defferent Click and add function
