Interestingly, if you set 'no-cache' on file downloads over an SSL
(https) connection where IE has a mime-handler defined (word/xls/pdf),
will throw spurious errors about being unable to cache the file, even
when trying to 'save target as'.

This isn't a catalyst issue, but an IE 'feature'- might be useful to
know before it bites, though.
