Maybe Request.hostname is a bad example. In general you can provide a
query that is more efficient than actually trying to do it. The
example to which I linked in the previous email was about an OpenFile
method that can throw FileNotFound paired with FileExists that returns
a boolean. I'd bet FileExists is not implemented in terms of OpenFile.

I'll stop here since I'm a troll :-P
