-or-

The Url property is not a valid URL.

The intersection of two permissions is a permission that describes access to the URLs they both describe in common. Only a demand that passes both original permissions will pass the intersection. For example, the intersection of a permission that represents access to http://www.fourthcoffee.com/process/grind.htm and a permission that represents access to http://www.fourthcoffee.com/* is a permission that represents access to http://www.fourthcoffee.com/process/grind.htm.

UrlIdentityPermission supports set operations (IsSubsetOf, Intersect, and Union) only when the current permission is equal to the specified permission object or when one of the permissions uses the wildcard operator ("*").
