IMetadataInfo::GetVrToken Method

Retrieves an IHttpTokenEntry interface for the impersonation account that is configured for a virtual directory.

Syntax

virtual IHttpTokenEntry* GetVrToken(  
   VOID  
) = 0;

Parameters

This method takes no parameters.

Return Value

A pointer to an IHttpTokenEntry interface.

Remarks

When creating a virtual directory in IIS that points to a network share, you can specify the impersonation user name and password that IIS will use to connect to the network share when IIS processes requests. You can then use the GetVrToken method to retrieve an IHttpTokenEntry interface for the impersonated user.

Example

The following code example demonstrates how to use the GetVrToken method to create an HTTP module that retrieves an IHttpTokenEntry interface for the impersonation account that is configured for a virtual directory. The module converts the user token to a string and returns the string to the Web client.

[!code-cppIMetadataInfoGetVrToken#1]

Your module must export the RegisterModule function. You can export this function by creating a module definition (.def) file for your project, or you can compile the module by using the /EXPORT:RegisterModule switch. For more information, see Walkthrough: Creating a Request-Level HTTP Module By Using Native Code.

You can optionally compile the code by using the __stdcall (/Gz) calling convention instead of explicitly declaring the calling convention for each function.
