UrlIdentityPermission Constructor (String)
Initializes a new instance of the UrlIdentityPermission class to represent the URL identity described by site.
Assembly: mscorlib (in mscorlib.dll)
The complete URL is considered, including the protocol (HTTP, HTTPS, FTP) and the file, for example: http://www.fourthcoffee.com/process/grind.htm/.
URLs can be matched exactly or by a wildcard in the final position, for example: http://www.fourthcoffee.com/process/*. URLs can also contain a wildcard ("*") prefix at the dot delimiter. For example, the URL name string http://www.fourthcoffee.com/process/grind.htm/ is a subset of http://*.fourthcoffee.com/process/grind.htm/ and http://*.com/process/grind.htm/.
Starting with the .NET Framework version 2.0, for performance reasons, an invalid URL does not cause an argument exception at the time the new class instance is created. The argument exception will occur when one of the set operations (Union, Intersect, or IsSubsetOf) is executed. A demand on the permission causes IsSubsetOf to be called by the security infrastructure. The demand will fail because of the argument exception, resulting in a SecurityException being thrown. In this case, the original ArgumentException exception will not be seen.
