download functionality

Hi.

 I am developing an application where users can upload videos.
 I need to implement the functionality to download the videos on the end users desktop.
 i.e. i need to provide download link that will download the videos on the user's system

 Any pointers ,how can i achieve this?

Thanks

send_file is your friend.

Thanks Kitto,
It solved my problem.
Previously i used send_data but it didn’t work.
Then i used send_file.
Cheers.
