Redirecting user to admin page with usernamed url

Question

Hello,

I have a directory structure

root->admin-> admin operations

admin page inherited from a ase page with principla security.demand role = "Admins"

i am usinf forms authantication mode.

i have also put a web.config file in admin folder, restricting other users.

it is working normaly with siteroot/admin.

I want to setup a mechanism to admin like siteroot/username/admin

I can redirect to page admin (urlrewriting) but it gives security error, it should redirect to login page instead of if user did not sign in.

i give all users a page witt url siteroot/username, and i want to edit their page with url siteroot/username/admin
