Les, ignore d/b. Think of you submitting, from your browser, a request for
something, and the transaction is incomplete, and it gets to the server,
and instead of getting what it was allowed to, it gets something below
that level, that it's *not* allowed to get, and you really *don't* want
accesible, but it can do it as apache....

Or something as trivial as requesting something, and your email address is
truncated.

BEA doesn't make Big Bucks for Tuxedo, for example, only for d/b
transactions.
