The complete URL is considered, including the protocol (HTTP, HTTPS, FTP) and the file. For example, http://www.fourthcoffee.com/process/grind.htm is a complete URL.
The scope of the declaration that is allowed depends on the SecurityAction that is used.
The security information declared by a security attribute is stored in the metadata of the attribute target and is accessed by the system at run time. Security attributes are used only for declarative security. For imperative security, use the corresponding permission class.
The following example of a declarative attribute shows the correct way to request UrlIdentityPermission and states that you must have the specified URL identity to run your code. Code will execute only if run from the specified URL.
<Assembly:UrlIdentityPermissionAttribute(SecurityAction.RequestMinimum, _ Url := "http://example.microsoft.com/sample/sampleapp.exe")> 'In Visual Basic, you must specify that you are using the assembly scope when making a request.
/** @assembly UrlIdentityPermissionAttribute(SecurityAction.RequestMinimum,
Url = "http://example.microsoft.com/sample/sampleapp.exe")
*/
// In VJ#, you must specify that you are using the assembly scope when
// making a request.
The following example shows how to demand that the calling code has the specified URL identity at link time. Code will execute only if run from the specified URL.
<UrlIdentityPermissionAttribute(SecurityAction.Demand, _ Url := "http://example.microsoft.com/sample/sampleapp.exe")> _ Public Class SampleClass
/** @attribute UrlIdentityPermissionAttribute(SecurityAction.Demand,
Url = "http://example.microsoft.com/sample/sampleapp.exe")
