Removes a specific fragment from the cache.
virtual HRESULT RemoveFragmentFromCache(
__in WCHAR* pszFragmentName
) = 0; pszFragmentName
[IN] A pointer to a WCHAR that specifies the fragment to be removed from the cache.
An HRESULT. Possible values include, but are not limited to, those in the following table.

Developers can use the AddFragmentToCache, ReadFragmentFromCache, and RemoveFragmentFromCache methods, respectively, to add HTTP_DATA_CHUNK structures to the fragment cache, or to retrieve and remove HTTP_DATA_CHUNK structures from the cache. These methods give developers a small degree of custom functionality to use the built-in IIS cache for storing and retrieving data fragments in the cache.
Note
Http.sys manages and owns the fragment cache. At any time, Http.sys may override or delete information that you directed to be stored. There is currently no way to lock information in the fragment cache as nonvolatile information.
