.Net Security - Not 'all' pages

P: n/a
I am fighting with XP-Pro and VS.Net trying to allow some of the pages in my
application to be accessable by 'all' I am using <authentication
mode="Forms" /> and if I Login - everything works fine. My code comes from
a walkthrough (I am learning) and I am currently using
(User.Identity.IsAuthenticated) in the Login.aspx page to validate UserID
against my database (I like it).
What I need is a 'simple' method by which I can set some of the generic
pages to be accessable by 'all' visitors, even those Not LogedIn. Ken
Dopierala Jr. answered another post and suggested I use <location
path="directory"> to allow Role based access to some directories and then
just <allow users="*" />.
PLEASE - There must be a 'simple' way I can desiginate a page as generic and
not require authorization to access these generic pages.
Can anyone give me some 'detail' advice on how to accomplish this?
Thanks,
Paul

Hi Paul,

I totally recommend against doing this and instead using a Roles based
security system. But here is a workaround. Create a class and add this
code:

Option Strict On
Option Explicit On

Imports System
Imports System.Web
Imports System.Web.UI

Public Class MyBasePage
Inherits System.Web.UI.Page

Protected Overrides Sub OnLoad(ByVal e As System.EventArgs)
If (User.Identity.IsAuthenticated = False) Then
Response.Redirect("Login.aspx")
End If
End Sub
End Class

Have every page that you want to have protected inherit from this page. For
every page that you want generic have it still inherit from
"System.Web.UI.Page". Now, if a user isn't authenticated, and this is a
protected page, they will be sent to Login.aspx. Remember to set your
<authentication> tag to allow everyone, you are no longer using the the
ASP.Net built in management for authentication. I wouldn't do it this way
and in the end you'll be totally screwing yourself over. But, this will at
least do what you want it to until you switch over to Roles based
authentication. Good luck! Ken.

Ken,
I am following an example from WebMatrix called MyPics - - it allows
authorized users to (Login with UserID & Password - verified against the User
database) and to Upload pictures - and I thought anyone could view the
pictures. I am trying to get a site up (for the practice & learning) that
will allow anyone to look around, but allow Logined users more access to
secure pages.
The Login.aspx.cs is:
using System;

I want to do it the 'right' way - but I am not sure I really want Role based
security (do I?) I like the User ability to 'Register' and then have access
to 'secure' functionality.

Thanks so much for your time.

Hi Paul,

The response I gave you before will do the trick. I didn't know you were
using C#. Here is how to do it.

1) Create a class:

using System;
using System.Web;
using System.Web.UI;

public class MyBasePage : System.Web.UI.Page {

override void OnLoad(System.EventArgs e) {
if (User.Identity.IsAuthenticated == false) {
Response.Redirect("Login.aspx");
}
}

}

2) Declare protected pages like this:

public class ProtectedPage : MyBasePage {
}

3) Declare public pages like this:

public class PublicPage : System.Web.UI.Page {
}

If your user isn't logged in and goes to a protected page he will be
redirected to the login page. Any page that derives from System.Web.UI.Page
will let everyone see it. In your Web.config make sure your <authorization>
tag looks like this:

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

Here is a tutorial on roles based:

http://www.xoc.net/works/tips/forms-authentication.asp

Roles based lets you protect entire folders based on user type. You still
have them sign up and when they do you assign them a role. With the code
above you can implement it the way they are doing it in your example. Good
luck! Ken.

}
}

I like your suggestion - and I know we are close.

Hi Paul,

Try:

protected override void OnLoad(System.EventArgs e)

Instead of:

override void OnLoad(System.EventArgs e)

I think it needs to be that, this way derived classes can call it. You also
might need to put: MyBase.OnLoad(e) as the first line in the page load event
of your derived classes but I'm not totally sure. I'm also not sure if C#
uses MyBase or something else to reach it's parent class. Ken.

Hi Paul,

The response I gave you before will do the trick. I didn't know you were using C#. Here is how to do it.

1) Create a class:

using System;
using System.Web;
using System.Web.UI;

public class MyBasePage : System.Web.UI.Page {

override void OnLoad(System.EventArgs e) {
if (User.Identity.IsAuthenticated == false) {
Response.Redirect("Login.aspx");
}
}

}

2) Declare protected pages like this:

public class ProtectedPage : MyBasePage {
}

3) Declare public pages like this:

public class PublicPage : System.Web.UI.Page {
}

If your user isn't logged in and goes to a protected page he will be
redirected to the login page. Any page that derives from System.Web.UI.Page will let everyone see it. In your Web.config make sure your <authorization> tag looks like this:

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

Here is a tutorial on roles based:

Roles based lets you protect entire folders based on user type. You still have them sign up and when they do you assign them a role. With the code above you can implement it the way they are doing it in your example. Good luck! Ken.
