With next code I want to send bynary data to php script:

lcData = filetostr("MyFile.dat")
loHTTP = CREATEOBJECT('WinHttp.WinHttpRequest.5.1')
loHTTP.Open("POST", "http://www.MySite.com/MyScript.php", .f.)
loHttp.setrequestheader("content-type","application/x-www-form-urlencoded")

IF NOT loHTTP.Send( lcData )
MESSAGEBOX( loHTTP.ErrorCode+loHTTP.ErrorMsg)
ENDIF


In this script $HTTP_RAW_POST_DATA gets only first 5 symbols
Maybe problem is connected with next info
from loHTTP.GetAllResponseHeaders() :

Why "Content-Type" is text/html ?

Thanks in advance for any help
