This section describes the Web Server Core and integrated request-processing pipeline enumerations.
In This Section
The following table lists the enumerations exposed by the integrated request-processing pipeline.
| Enumeration | Description |
|---|---|
| CACHE_OPERATION | Defines the enumeration values for cache operations. |
| GLOBAL_NOTIFICATION_STATUS | Defines the return values for global-level notifications. |
| HTTP_TRACE_TYPE | Determines what data type the HTTP_TRACE_EVENT_ITEM structure maintains. |
| REQUEST_NOTIFICATION_STATUS | Defines the return values for request-level notifications. |
Remarks
All global-level notification handlers are required to return a value from the GLOBAL_NOTIFICATION_STATUS enumeration, and all request-level notification handlers are required to return a value from the REQUEST_NOTIFICATION_STATUS enumeration.
You can use the values from the HTTP_TRACE_TYPE enumeration to define the type of data that is contained within an HTTP_TRACE_EVENT_ITEM structure.
When you call the ICacheProvider::GetCacheOperation method, values from the CACHE_OPERATION enumeration indicate the resulting cache event.
