perhaps.  but what's looks like is happening here is that the webserver is
checking for the existence of index.html by becomeing an http client for a
moment, and making a connection via the gateway back to the same url that
was requested of it.  the idea being that if it doesn't exist, it will
dynamically build an index.html containing a list of files.  however,
since you can't reach a nated service from the inside, that fails.  very
strange.  if index.html does NOT exist, all works fine.  if it DOES exist,
it craps out.
