If so, the NetCodeGroup dynamically generates a permission set that contains a System.Net.WebPermission that grants access to the web site specified in the Url evidence.

Members of a NetCodeGroup are tested for membership against all of its child code groups. The final permission set granted by the NetCodeGroup is the union of its permission set and the permission sets of the children to which the assembly or application domain also ...
