IHttpTokenEntry Interface
Extends the IHttpCacheSpecificData interface by adding token-specific information for tokens that are cached on a server.
Syntax
class IHttpTokenEntry : public IHttpCacheSpecificData
Methods
The following table lists the methods exposed by the IHttpTokenEntry class.
| Name | Description |
|---|---|
| DecrementTTL | (Inherited from IHttpCacheSpecificData.) |
| DereferenceCacheData | (Inherited from IHttpCacheSpecificData.) |
| GetCacheKey | (Inherited from IHttpCacheSpecificData.) |
| GetFlushed | (Inherited from IHttpCacheSpecificData.) |
| GetImpersonationToken | Returns the impersonation token for a user. |
| GetPrimaryToken | Returns the primary token for the process that is servicing a request. |
| GetSid | Returns the security identifier for a user. |
| ReferenceCacheData | (Inherited from IHttpCacheSpecificData.) |
| ResetTTL | (Inherited from IHttpCacheSpecificData.) |
| SetFlushed | (Inherited from IHttpCacheSpecificData.) |
Derived Classes
This interface contains no derived classes.
Remarks
CGlobalModule derived classes that register for GL_CACHE_OPERATION events receive an ICacheProvider pointer as a parameter on the CGlobalModule::OnGlobalCacheOperationvirtual method. You can retrieve an IHttpCacheSpecificData pointer by calling the ICacheProvider::GetCacheRecord method and, in some cases, you can downcast this IHttpCacheSpecificData pointer to an IHttpTokenEntry pointer.
For more information on downcast rules, see ICacheProvider::GetCacheRecord.
Example
The following code example demonstrates how to create a global module that listens for GL_CACHE_OPERATION and GL_CACHE_CLEANUP events and then writes the IHttpTokenEntry information to the Event Viewer.
Warning
IIS 7 generates a large number of events in the Event Viewer. To avoid a log overflow error in a production environment, you should generally avoid writing cache information to the event log. For demonstration purposes, this code example writes an entry to the Event Viewer in debug mode only.

The above code writes a new event to the Event Viewer, where the Data box holds XML similar to the following.
<cacheProvider>
<tokenEntry
impersonationToken="valid"
primaryToken="valid"
sid="true"/>
</cacheProvider>
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.
