IIS Log Contains Wrong Data When ISAPI Uses Default for File Size

When an ISAPI application uses the HSE_TF_INFO data structure to issue a ServerSupportFunction(HSE_REQ_TRANSMIT_FILE), it is allowed to specify 0 as the value of the HSE_TF_INFO::BytesToWrite meaning, "send all file."If zero is specified, then the sc-bytes value in the Internet Information Services (IIS) log file is invalid, because it reflects only the headers and not the entire transfer size.
IIS does not log the total size of the file that is actually transferred,but uses the size argument transmitted to the TransmitFile API.
