One feature of the StaticFile class that is not present in
the code you posted earlier is that it returns a FileStream
instead reading the file into a string.  You might want to
do that even if you don't use the StaticFile and/or StaticDirectory
classes.

What is the obstacle to using names like "page.html" with
StaticFile/StaticDirectory?  Is it the "." in the name?
StaticDirectory seems to handle that with a _q_lookup(),
like the pattern you described.
