Hi,
To download file with the specific file name like song.mp3 as your
following url
http://192.168.1.105/download/servlet/download?filename=song.mp3
changed it with following url-
http://192.168.1.105/download/servlet/download/song.mp3?filename=song.mp3
.
So while downloading the extrapath song.mp3 will be the filename.
