> The problem is that the method "Stream.Read() or BinaryReader.Read()" may read less amount of bytes than the provided buffer size when the end of the stream has not been reached yet.
> For example.
> The file "File1.txt" of size 30K is requested by HttpWebRequest to download from a server and transfer it to Alfresco.
> HttpWebRequest returns System.Net.ConnectStream.
> The  buffer size to read from stream is 65K.
> In the current code the first read operation returns 4K from the stream and the condition "while (BufferSize <= readBytes)" finishes the read cycle.
> The problem can be fixed by the code below:
> using (var br = new BinaryReader(stream))
> {
>    var buffer = new byte[BufferSize];
>    int readBytes = 0;
>    while ((readBytes = br.Read(buffer, 0, BufferSize)) != 0)
>    {
>       writer.WriteBase64(buffer, 0, readBytes);
>    }
> }
