So... I could store the TIF in an IFS directory (for example, in a folder in
my Win2000 Server on my iXA).  Then, by using properly coded Java
programming I should be able to have an object on the web page (servlet,
JSP, whatever it needs to be) which, when activated, will cause the doc to
display (or redirect the user to another page if they're not authorized).
And they would have no other means to access the image except thru that Java
object.  No?
