Depends on the browser.  But yes.  And that's a crappy filename for the 
Q12010 report!

Is it now?  You have to do a redirect on the server side, increase 
latency for the user, etc.  For what purpose, given that you just want 
to specify the filename and there is already a mechanism for that?

Because the URI is generated based on a form the user fills out, and no 
one ever sees the actual URI?

"better" byt what metric?

That's great, and I'm happy you're willing to impose costs on your users 
so you don't have to use it.  But others may wish to make different 
tradeoffs here.
