4.1.3 Share Header

Upon receipt of the reply Socket Connect header (section 2.2.1), the Share Sender sends the Share header (section 2.2.2). The Share Sender has the size of the OPC package to be sent, so it sets the TotalContentSizeEstimate field of the Share header appropriately. In this case, the Share header contains the following values in byte order: 0x0A, 0x00, 0xF4, 0x01, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00. The following packet diagram shows the values in little-endian 16-bit word order.
