ASP.NET 2.0 RedirectFromLoginPage

Hi,

I cannot seem to resolve an issue with this command.

If I attempt to access a page from the web site without first logging in, it sends me to the login page (so far so good).

However, after entering my credentials I do NOT get redirected to the originally requested page.

I have thus far not been able to find a solution so your help would be appreciated.

My setup...

I have a Custom login operation.

Then i am simply executing:

    FormsAuthentication.RedirectFromLoginPage("test", False)

I have also tried:

    FormsAuthentication.SetAuthCookie(txb_User.Text, False)
    FormsAuthentication.RedirectFromLoginPage(txb_User.Text, False)

Web.Config section:

    <authentication mode="Forms">
       <forms name=".iMedia" loginUrl="index.aspx" defaultUrl="main.aspx"  timeout="59" protection="All" path="/" slidingExpiration="False"/>
    </authentication>thanks.

Hi
in an web application written in ASP.NET 1.1 (Studio 2003) I used Forms Authentication
without an database, but with an login page and I got always redirected to the originally
requested page.
I hope my example will help you successful

Web.config
==========
<authentication mode="Forms">
        <forms name=".ASPXAUTH" path="/" protection="All" timeout="20">
	    <credentials passwordFormat="SHA1">
	        <user name="admin" password=""/>
	        <user name="guest" password=""/>
	    </credentials>
        </forms>
</authentication>
 
Login.aspx
==========
<form id="Form1" method="post" runat="server">
	<H3 align="center">PC-Administration Login</H3>
	<P align="center">Please enter a user name and a password</P>
	<P align="center">Username: guest</P>	'You can only read contents
	<P align="center">Password: guest</P>
	<br>

	<TABLE id="Table1" style="POSITION: absolute; TOP: 300px" cellSpacing="1" cellPadding="1" width="100%" border="0">

End Sub
 
Private Sub btnLogOn_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnLogOn.Click
    If FormsAuthentication.Authenticate(txtUserName.Text, txtPassword.Text) Then
         FormsAuthentication.SetAuthCookie(TxtUserName.Text, False)
         Response.Redirect("Default.aspx")
    Else
         btnLogOn.Text = "Login invalid"
    End If
End Sub

Hi,

Thanks for your post however I am using 2.0 and my own login method (i query a database for user and password).

Also, your example does not look like it will redirect to the originally requested page (i.e. a page that requires authentication).

Your example will always redirect to Default.aspx.

thanks.

Hi,
it redirect to Default.aspx (Startpage from the webapplication) only if the login was successful !
Otherwise you stay always on Login.aspx.
