Im working on a standalone browser library for Kobo Touch users.
I have a big problem about the download function. When ever i open a Link to an .epub-File, the browser does not download it. It just opens the file cryptik inside the browser that freezes after that. First i thought: there is no way it could be solved. But gutenberg.org does have a solution for that. Also it works inside the calibre library that you reach through your webbrowser.

How do they get the files to download? Or easier: How do they bring up the box that asks if file should be downloadet or not?

Sorry for my bad english
