There are more choices...

Three, (a variation of two) return with a page containing a list of 
reports 1-4, use meta-refresh to automatically start the download of the 
first report, and allow the user to click on the others to initiate them.

Four, put the 4 reports into a .zip file and download it

Five, (this one depends on client side scripting, and is theoretical (I 
haven't tried it)), return a page that uses scripting to initiate 4 
requests, one for each report; each would pop up a dialog to save the 
report when the download response arrives.  If anyone gets this one 
working, please share the results :)  I've been wanting to try it for a 
while, but have had higher priority projects...
