IInternetProtocolSink::Switch
HRESULT Switch(
    [in] PROTOCOLDATA *pPROTOCOLDATA
);
Passes data from an asynchronous pluggable protocol's worker thread intended for the same asynchronous pluggable protocol's apartment thread. The IInternetProtocolSink interface should pass this data, without modification, back to the asynchronous pluggable protocol by calling its IInternetProtocolRoot::Continue method.
Returns S_OK if successful, or E_FAIL if called when an asynchronous operation is pending.

pPROTOCOLDATA
Address of a PROTOCOLDATA structure containing the data to be passed back to the apartment thread.

Asynchronous pluggable protocol handlers may operate asynchronously in a separate worker thread. This method allows the protocol handler to pass data back to the apartment (or user interface) thread it was created on.
