How to check the binary contents of the uploaded file. For example, to prevent the fake file being uploaded, because I really want to check if the uploaded file is really the pdf file or image file. How can you do it? I realise checking the mime type of the file is not enough as the file extension can still be renamed. HOw can i do it? -- View this message in context: http://www.nabble.com/Check-the-mime-type-of-uploaded-file-and-its-binary-content-tf3776119.html#a10677590 Sent from the Wicket - User mailing list archive at Nabble.com.
