Hello Chuck,
From your description, in your ASP.NET forms authentication secured web
application, you want to make those users (that will be redirected to the
login page) see different pages depend on whether they're unauthenticated
or doesn't have sufficient permission(role), correct?
If this is the case, I think the simplest and most convenient means is to
customize your login page and check the HttpContext.Current.User.Identity
to see whether it is authenticated. Because if a user is redirect to login
page due to unauthenticated, the Identity should be unauthenticated too,
while if the user is redirected due to unsufficient permission, it should
already has an authenticated identtiy. e.g.
=====in login page code==============
protected void Page_Load(object sender, EventArgs e)
{
if (Context.User.Identity.IsAuthenticated == true)
{
Server.Transfer("~/AccessDeniedPage.aspx");
//or use response.redirect(....)
}
}
==============
Also, you need to make sure you add authorization setting to allow all
authenticated users to access the "AccessDeniedPage" in web.conifg
====in web.config======
.............
<location path="AccessDeniedPage.aspx">
<system.web>
<authorization>
<deny users="?"/>
</authorization>
</system.web>
</location>
...................
============================
Hope this helps.
Sincerely,
