Question

I’m developing web site using asp.net. In my web site after login i set session for the logged user for my web site need. and on each page i checked whether that session is null or having value and depending on the value i redirected to the login page.

My issue is that after login i want to redirect to the previously browsed web page and i done it by using following way-

code on the particular page for checking session value-

if (Session["EmployeeID"] != null)
    {

    }
    else
    {
        Response.Redirect(ResolveUrl("~/login.aspx?IsTimeout=1"), true);
    }

code on the login page-

If Request.QueryString("IsTimeout") IsNot Nothing Then
   If Request.QueryString("IsTimeout") = "1" Then
      Login1.DestinationPageUrl = Request.UrlReferrer.ToString()
   End If
End If

Is there any other way to do this in correct way?

I’m not sure about the correct way… but im doing it something like this..

I have a function that request a login page and passes a parameter of the referrer

    protected void RequestLogin()
    {
        string OriginalUrl =  HttpContext.Current.Request.RawUrl;
        string LoginPageUrl = "~/LogIn.aspx";
        HttpContext.Current.Response.Redirect(String.Format("{0}?ReturnUrl={1}", 
        LoginPageUrl, OriginalUrl));
    }

and here is the redirection after log in.

   if (this.Request.QueryString["ReturnUrl"] !=null) 
   {
        this.Response.Redirect(Request.QueryString["ReturnUrl"].ToString());
   }
   else
   {
        this.Response.Redirect("Default.aspx");
   }
