Greetings Anonymous Monk,

What !1 referenced looks very cool and is a much better option than my idea, but for completeness: What has worked for me in the past is to specify some throw-away query parameter that is always changing. For example:

my $url = 'yourscript.cgi?data=realdata&ignore=' . time . rand
# Then feed $url to links in refering pages
[download]

Every time you click a link from a refering page (which itself has to be a script because it generates the random URL), you get a new unique URL for which IE has no cache. Just ignore the ignore parameter. It's hokey; it's stupid; it's a hack, but it has the value of working.
