Calculating correct relative to URLs when using publisher is a PITA
because multiple URLs can refer to the same resource. See prior
commentary on this:


The link includes code which may be of some use in at least
reliably calculating a relative URL to the directory the PythonHandler
directives was defined for. Knowing that, you can then extend
it to parent or sibling directories as appropriate using posixpath.join().
