Is there any way, by the use of the Browser app or the Mojo SDK, to force the download of a file?

This is a major part of an app I am developing for the Pre (porting from Windows XP/Vista that does everything using .NET to a WebOS Version that relies on a Linux server for part of the job and then downloads the file from the server) and without this crucial addon, I will either have to wait for native app support (with the ability to install linux software) or rely on apps like FileCoster to handle the downloading, which would be out of the question.

Thanks in advance.
