Ext net elements are not shown when authentication added

[Ismail]

Ext net UI elements are not shown after I added authentication in web.config to redirect all unauthorized access to the login page. Everything works fine if I remove this constraint. Is this normal Ext net behaviour? Any help on how to solved this would be much appreciated. Below is my login form which displays an empty page.

<ext:ResourceManager runat="server" />
    <ext:Viewport runat="server">
        <LayoutConfig>
            <ext:VBoxLayoutConfig Align="Center" Pack="Center" />
        </LayoutConfig>
        <Items>
            <ext:FormPanel
                runat="server"
                Title="Login"
                Width="400"
                Frame="true"
                BodyPadding="13"
                DefaultAnchor="100%">
                <Items>
                    <ext:TextField
                    ID="txtUsername"
                    runat="server"
                    FieldLabel="Username"
                    AllowBlank="false"
                    BlankText="Your username is required."
                    />
                <ext:TextField
                    ID="txtPassword"
                    runat="server"
                    InputType="Password"
                    FieldLabel="Password"
                    AllowBlank="false"
                    BlankText="Your password is required."
                    />
                    <ext:Checkbox runat="server" FieldLabel="Remember me" Name="remember" ID="chkRememberMe"/>
                </Items>
                <Buttons>
                    <ext:Button ID="btnEnter" runat="server" Text="GiriÅŸ Yap" Icon="Accept" OnDirectClick="btnEnter_DirectClick"/>
                    <ext:Button ID="btnPassword" runat="server" Text="Åžifremi Unuttum" Icon="LockKey">
                 </ext:Button>
                </Buttons>
            </ext:FormPanel>
        </Items>
    </ext:Viewport>
</body>

WEb.config

  <authentication mode="Forms">
       <forms name=".ASPXFORMSLOGIN" loginUrl="LoginScreen.aspx"
       timeout="30" slidingExpiration="true" />
    </authentication>
    <authorization>
      <deny users="?"/>
      <allow users="*"/>
    </authorization>

Hello!

Edit Global.asax
You need to update your Application_AuthenticateRequest function to IGNORE the ext elements. Then it will work fine!

good luck!

        protected void Application_AuthenticateRequest(object sender, System.EventArgs e)
        {
            string url = HttpContext.Current.Request.RawUrl.ToLower();
            if (url.Contains("ext.axd"))
            {
                HttpContext.Current.SkipAuthorization = true;
            }
}

Thank you Z for the reply. I ended up using a normal login form but it will try ignore the ext code as you suggested
