After your reply I did some more tests with the following conclusions.
1. I was wrong about perl. IE behaves the same with the perl equivalent
script,
but requires the user to cancel 2 times. After the second time, you cannot
try anymore.
2. The source of the problem seems to be Internet Explorer and not the
server nor the
scripting language.
I have tested the same script under win2k with both IIs and apache
and both perl and php with the same results.
I have also tested both php and perl scripts on a linux running apache
1.3.14. Still the same problem.
After two attempts to download, then hit ok and at the "save as" dialog, hit
cancel, IE becomes useles.
I haven't tried asp, but something tells me it will make no difference.
Thanks.
