* getRawInputStream() : Return an InputStream to the raw data with any Content-Transfer-Encoding
* intact. This method is useful if the "Content-Transfer-Encoding" header is incorrect or corrupt,
* which would prevent the getInputStream method from returning the correct data. In such a case
* the application may use this method and attempt to decode the raw data itself.
