responseBody Property (ServerXMLHTTPRequest/IServerXMLHTTPRequest)
Represents the response entity body as an array of unsigned bytes, namely a SAFEARRAY of type VT_ARRAY | VT_UI1. This contains the raw undecoded bytes as received directly from the server. Depending on what the server sent, this can appear as binary-encoded data (UTF-8, UCS-2, UCS-4, Shift_JIS, and so on).
