I have a website that uses ASP.NET forms authentication using .Net 4.0 on IIS 7. I have secured the site using a third party single-sign on provider (jasig CAS), and it all works well.
The default documents list in IIS has Default.aspx at the very top.
The default page of the website is Default.aspx and it is opened to the public with the below snippet from my web.config, again this works as expected when I navigate directly to the page.
<location path="Default.aspx">
<system.web>
<authorization>
<allow users="*" />
</authorization>
</system.web>
</location>
The problem that I'm having is that when I navigate to the root of my website ie www.mydomain.com rather than www.mydomain.com/default.aspx I am redirected to the forms authentication page.
Surely this is the same page, and is subject to the same authorization rules?
I am stuck on this, and do not know where to turn.
