Url accessible but NOT downloadable

[jaywhy13]

Is that possible. Say I have a file...
http://somesite.com/thefile.txt
That's evidently url accessible, but I can I make it so that you can't download it?

I know it's a dumb question... however the real question is this, I need to overlay some confidential data via KML on Google Maps... however I don't want any user out there to be able to download the KML file. How can I achieve this?

this could be totaly wrong:

I remember I read somewhere that WEB-INF directory is not accessible by default the way that someone could pick up the file, put it there.

In java there is something like <JSP:include file .....

and here u go, no access for anybody
