This is one of those issues that just can't be solved with simple HTTP and HTML. There isn't a response sent to the server to tell it every single download was successful (or at least not sent back to the web application ... TCP makes sure the last bytes get to the other side successfully or an error occurs, but the applications on the server side can't tell this or at least I don't know how). Then to make the situation more difficult there is no defined event for tying into the HTTP process for when a certain download has occurred successfully. So, one has to use a download manager of some kind to more easily manage things like this. This could be a signed java applet or shockwave file or a COM object (not cross platform so I wouldn't recommend that, but you might think it's ok if you force IE and windows). One could more easily tell if an upload had finished because you at least have a defined form element you can access through DOM, get the name, and then monitor the upload progress.
