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 Arpit

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. Arpit
