I am new inasp.net, I am giving form authentication to my web site for that i have
written following code in web.config file.On compilation it is giving me error.

can any body help me out.

thanks & regards

the code goes here..

<authentication mode="Forms"/>

<forms name="formsauth1" loginUrl="Login.aspx" protection="all" timeout="30" path="/">

<location path="Login.aspx"> [This can also be a folder]

<authorization>
<deny users="?" />
</authorization>

</location>

you closed the authentication tag too early...


<authentication mode="Forms" />

This is what I use:

Code:

---

<authentication mode="Forms">
    <forms loginUrl = "Login.aspx"/>
</authentication>

<authorization>
    <allow users="?" />
</authorization>

---

And then in my login page I have:

VB Code:

Imports System.Web.Security
 
Private Sub btnLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogin.Click
    Dim objTicket As FormsAuthenticationTicket
    Dim objCookie As HttpCookie
    Dim strReturnURL As String
    If ValidateLogin() Then
        objTicket = New FormsAuthenticationTicket(txtUsername.Text, False, 30)
        objCookie = New HttpCookie(".ASPXAUTH")
        objCookie.Value = FormsAuthentication.Encrypt(objTicket)
        Response.Cookies.Add (objCookie)
        strReturnURL = Request.Params("ReturnURL")
        If strReturnURL Is Nothing Then
            Response.Redirect ("Main.aspx")
        Else
            Response.Redirect (strReturnURL)
        End If
    Else
        lblMessage.Visible = True
        lblMessage.Text = "Invalid username/password."
    End If
End Sub

Does that help?
