This topic describes the constants that are defined in the Httpcach.h header file.
The following constants are used for returning values from the IHttpCacheKey::GetCacheName method for interfaces defined in the Httpcach.h file.
| Constant | Value | Description |
|---|---|---|
| FILE_CACHE_NAME | L"FILE" | The IHttpCacheKey pointer may be safely downcast to an IFileKey pointer. |
| TOKEN_CACHE_NAME | L"TOKEN" | The IHttpCacheKey pointer may be safely downcast to an IHttpTokenKey pointer. |
| URI_CACHE_NAME | L"URI" | The IHttpCacheKey pointer may be safely downcast to an IUriKey pointer. |
Before you perform any downcast operation, always verify that the cast is correct to guarantee correct program behavior. Consider using the dynamic_cast operator whenever possible when you perform a downcast operation.
