SaveAs Method of ByteArray class - Write binary data to a file

ByteArray - Save the posted data.

<%
  Set Binary = CreateObject("ScriptUtils.ByteArray")
  Length = CLng(Request.ServerVariables("HTTP_Content_Length"))
  Binary.ByteArray = Request.BinaryRead(Length)
  Binary.SaveAs Server.MapPath(".") & "\data.post"

  Response.Write "Request data (" & Binary.Length & " bytes): <br><pre>"
  Response.Write Binary.String
  Response.Write "</pre>"
%>
<form method=post>
<input value=XXXXXXXXXXX NAME=A>
<input type=submit>
</form>

ByteArray - save unicode data (string) as utf-8 with BOM

'Save unicode string as UTF-8 with BOM

  '(after the 3bytes BOM header)

  'Or you can use ByteArray.HexString = "EFBBBF" in v> 2.14
