[mod_python] mod_python and execfile

If what you are trying to do is come up with your own mechanism for 
dispatching different URLs against different handlers in different files,
you should probably start by researching how mod_python.cgihandler,
mod_python.publisher, mpservlets and Vampire work as they all provide
this basic feature in various ways

You will find mod_python.publisher and mod_python.cgihandler as a
part of mod_python itself. As to mpservlets and Vampire, you can
find them at:

  http://www.dscpl.com.au/projects/vampire

A quick way of doing it (untested) would be:

  from mod_python import apache
  import os

  def handler(req):
      directory = os.path.dirname(req.filename)
      name = os.path.splitext(os.path.split(req.filename)[1])[0]
      module = apache.import_module(name,path=[directory])
      return module.main(req)

Then in the script file:

  def main(req):
     req.content_type = "text/plain"
     req.send_http_header()
     req.write('Hello there!')
     return apache.OK

This will not necessarily work in all situations as it doesn't do all
the checks it should. You would be better off using one of the
other dispatchers available unless your plan is to learn by writing
your own.
