ASP.NET Forms Authentication with Windows Safari - asp.net

Question

Does anyone know why ASP.NET Forms Authentication does not work on windows safari, or better yet, how to get it to work? It seems like a very weird issue. When I use a login control (System.Web.UI.WebControls.Login) everything works fine, but if I try to do a custom Forms Authentication login when I call FormsAuthentication.RedirectFromLoginPage safari just sends me back to the login page as if I'm not authenticated whereas every other browser logs me in and sends me on my way.
protected void lnkLogin_Click(object sender, EventArgs e)
{
if (Membership.Provider.ValidateUser(txtUsername.Text, txtPassword.Text))
{
Session.Clear();
HttpContext.Current.Response.Cookies.Clear();
FormsAuthentication.SetAuthCookie(txtUsername.Text, true);
FormsAuthentication.RedirectFromLoginPage(txtUsername.Text, true);
}
}

Answer 1

Try either SetAuthCookie, or RedirectFromLoginPage. The redirect needs to know where to redirect to anyway (ReturnUrl), maybe that is your problem.
if (Request.QueryString["ReturnUrl"] != null)
{
FormsAuthentication.RedirectFromLoginPage("someuserid", false);
}
else
{
FormsAuthentication.SetAuthCookie("someuserid", false);
Response.Redirect("~/SomePage.aspx");
}

This works fine for me in Safari:
protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
{
//check login
User user = UserBAL.GetUser(Login1.UserName, Login1.Password);
//null and filled object check
if (user != null && user.Id > 0 && user.Roles != null && user.Roles.Count > 0)
{
e.Authenticated = true;
FormsAuthenticationTicket authTicket = new
FormsAuthenticationTicket(1, //version
Login1.UserName, // user name
DateTime.Now, // creation
DateTime.Now.AddMinutes(60),// Expiration
false, // Persistent
string.Join("|", user.Roles.ToArray())); // User ata
// Now encrypt the ticket.
string encryptedTicket = FormsAuthentication.Encrypt(authTicket);
// Create a cookie and add the encrypted ticket to the
// cookie as data.
HttpCookie authCookie =
new HttpCookie(FormsAuthentication.FormsCookieName,
encryptedTicket);
Response.Cookies.Add(authCookie);
//redirect
Response.Redirect(FormsAuthentication.GetRedirectUrl(
Login1.UserName,
false));
}
else
{
Login1.FailureText = "Login failed.";
}
}
