Thanks again... now the last idea I have is using the webbrowser. As fare as I know all the known security holes have been worked on

Anyhow, maybe somebody knows how to download a file that does not end in .AZW, .PRC, .MOBI OR .TXT. Solutions that use a jailbreaked Paperwhite do not help here because I try to undemo a Paperwhite. I played with php, but "header('Content-Type: application/x-mobipocket-ebook');" and "header('Content-Disposition: attachment; filename="update.bin"');" did not work. Downloading files work, but just if the filename has one of the above four file-endings. Is there any way to have a script in the prc, azw or mobi to change the file ending and take a file from the /mtn/us/documents folder one directory up?
Thanks
