Response.redirect And Refreshing A Page?

I'm trying to build a tray for users to download their selected items. I was wondering if anyone knows how to response.redirect a file (for the user to download) and check to see if the download was successful/unsuccessful, then have the asp page reload itself based on the result?

e.g. something like this:

if Session("FileName") <> "" Then 'a file is ready for download

response.redirect (Session("FileName"))

** check if download successful, then set
** the tray info accordingly and...

response.redirect thispage.asp
end if

Of course the second response.redirect never gets called, is there any other way I can do this?
