I'm assuming mod_python is in there someplace (?)

This is really a mod_python thing more than a Myghty issue; or
more precisely, an Apache issue more than either.

DirectoryIndex is a directive which gives the mod_dir Apache
module instructions on what files to red (e.g., index.html) when it
gets called to output content.  It is otherwise completely ignored
by the Apache core engine, mod_python, and Myghty.

But the problem you have really comes down to which handler
Apache is choosing to serve the URL.  If you're using SetHandler
without any restrictions (such as inside a <Files> section) then
mod_python will always get the request, rather than the built-in
default-handler (which is what then invokes mod_dir or mod_autoindex).

I'm not sure of the best way to do what you want.  But perhaps you
can do Apache internal redirects, by using the mod_python
r.internal_redirect() method.  Then exclude all files named "index.html"
from being handled by mod_python.

<Files index.html>
SetHandler None
</Files>

And in your dhandler:

<%python>
   if .....:
       # call normal myghty components, etc.
   else:
       # no myghty components match, fall back to index.html
       dir = os.path.dirname( m.request_path )
       r.internal_redirect('%s/index.html' % dir)
</%python>


You may also be able to play with returning apache.DECLINED
from the mod_python request object, but I suspect there are
too many tricks there to get it to work, especially since you're
inside Myghty which is sitting on top of mod_python.

Note...the above code is totally untested.
