I have a .NET membership control for Members to login.

It works fine except when I go to my homepage without the /home.aspx declaration. For example...

http://www.mydomain.com/

I've debugged some other code here and I've found that the HttpContext.Current.User object is NULL

http://www.mydomain.com/home.aspx works.

The problem here is even when I've logged on and go back to my homepage, it does not show I'm logged in, in fact the control at the top of my page is asking for a username and password.  If I move around the site it works, go back to home login again.

Has this got somethign to do with the umbracoBaseRequestModule?
Does anyone know how to stop this happening, I'm guessing its some configuration problem.

I could potentially create all links to home.aspx, but this is not good for SEO reasons, all homepage links be it in a menu or a company logo link, should return just to the domain and not domain/homepage.aspx.

Ideas?
