C# Login to my asp.net page

Apr 24th, 2009

Hello.

I am trying to make a C# application login on my ASP.NET page.

I am using a login control to check the login.

login.aspx

</body>
</html>

        </asp:Login>
    
    </div>
    </form>
</body>
</html>

And then I have the authentication in C#:

        protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
        {
            cTPDatabaseEngine.Initialize();
            if (cTPDatabaseEngine.Login(Login1.UserName, Login1.Password))
            {
                e.Authenticated = true;
            }
            else
            {
                e.Authenticated = false;
            }
        }
        protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
        {
            cTPDatabaseEngine.Initialize();
            if (cTPDatabaseEngine.Login(Login1.UserName, Login1.Password))
            {
                e.Authenticated = true;
            }
            else
            {
                e.Authenticated = false;
            }
        }

And then on my upload page I have this:

 Help with Code Tags 
 C# Syntax (Toggle Plain Text) 
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!User.Identity.IsAuthenticated)
            {
                Response.Redirect("login.aspx");
            }
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!User.Identity.IsAuthenticated)
            {
                Response.Redirect("login.aspx");
            }

Now I am trying to login using C#, I first found the input names of the login form using the sourcecode in Firefox:

<input name="Login1$UserName" type="text" id="Login1_UserName" />
<input name="Login1$Password" type="password" id="Login1_Password" />
<input name="Login1$UserName" type="text" id="Login1_UserName" />
<input name="Login1$Password" type="password" id="Login1_Password" />

And then I have this in my C# login application:

 Help with Code Tags 
 C# Syntax (Toggle Plain Text) 
            http.AddValue("Login1$UserName", username);
            http.AddValue("Login1$Password", password);
            http.AddValue("Login1$UserName", username);
            http.AddValue("Login1$Password", password);

Where username & password is my username & password.

I can login when browsing the site with firefox but not in my Application.

The ResponseCode I get is this:

 Help with Code Tags 
 C# Syntax (Toggle Plain Text) 
            if (rsp.StatusCode == HttpStatusCode.OK)
            {
                if (http.ResponseText.Contains("Username or password incorrect"))
                    Console.WriteLine("Your login details were wrong.");
                //return;
            }
            if (rsp.StatusCode == HttpStatusCode.OK)
            {
                if (http.ResponseText.Contains("Username or password incorrect"))
                    Console.WriteLine("Your login details were wrong.");
                //return;
            }

HttpStatusCode.OK.

I should get a HttpStatusCode.Found if i'm correct?

This is how the login is done

 Help with Code Tags 
 C# Syntax (Toggle Plain Text) 
                    req.ContentLength = data.Length;
                    st = req.GetRequestStream();
                    string s = Encoding.ASCII.GetString(data);
                    string test = s;
                    st.Write(data, 0, data.Length);
                    req.ContentLength = data.Length;
                    st = req.GetRequestStream();
                    string s = Encoding.ASCII.GetString(data);
                    string test = s;
                    st.Write(data, 0, data.Length);

Why do I get the HttpStatusCode.OK?
Is there something weird when using asp.nets login control to login using an application?

Problem is it won't even let me login, the code works when uploading a file without authentication, I have cookies set if I get any.

Anyone have any idea?
