Possible bug with TCP functions?

[Zonarius 0]

Maybe I'm doing something wrong, but please try this:

TCPStartup()
myGet("www.google.at", "/intl/de_at/images/logo.gif")
TCPShutdown()

Func myGet($host, $file, $headers = "")
    Local $req
    Local $ip
    Local $ms
    Local $fp
    Local $recv

    $req = "GET " & $file & " HTTP/1.1" & @CRLF
    $req &= "Host: " & $host & @CRLF
    $req &= $headers
    $req &= @CRLF

    
    $ip = TCPNameToIP($host)
    $ms = TCPConnect($ip, 80)
    TCPSend($ms, $req)
    Sleep(1000)
    $recv = TCPRecv($ms, 1000000)
    TCPCloseSocket($ms)
    
    $fp = FileOpen("logo.gif", 2)
    FileWrite($fp, BinaryToString($recv))
    FileClose($fp)
EndFunc   ;==>myGet

What I receive is this:

HTTP/1.1 200 OK
Content-Type: image/gif

A bit too little for a picture.

So I watched traffic with a tool and I do receive the complete image, but i don't get it with AutoIt.

Is this a bug or am I doing something wrong?

I would expect that you should open the file in binary mode and save the recieved data without converting it to a string

$recv = TCPRecv($ms, 1000000,1);force binary
    TCPCloseSocket($ms)
   
    $fp = FileOpen("logo.gif", 16+2);force binary
    FileWrite($fp, $recv);
    FileClose($fp)

but that still doesn't work.

This works

inetget("http://www.google.at/intl/de_at/images/logo.gif","logo2.gif")

but that might not be any help.

It works with inetget, but it has to work with the TCP functions, doesn't it?
