Yes, it works correctly.

right. It doesn't work . I create a test directory, and test as following:

<Directory "/data/HTTPD/htdocs/t">

  AddHandler mod_python  .m .cgi .py
  #PythonHandler mod_python.psp
  PythonHandler myhandler
  PythonOption session_dbm /opt/tmp/mp_sess.dbm
  PythonPath "['/data/HTTPD/py_api']+['/data/HTTPD/htdocs/t']+sys.path"
  PythonDebug On
  Options Indexes FollowSymLinks
  Order deny,allow
  Allow from all

</Directory>

Create a  myhandler.py file in t directory:
from mod_python import apache
import anydbm

def handler(req):
     req.content_type = 'text/plain'
     db = anydbm.open("/tmp/mp_sess_test.dbm",'c')
     db.close()
     req.write('test ok')
     return apache.OK

when accessing by  http://myserver/t/myhandler.py.  An error
hanppen as following(the t directory 's permissions is 777.)

Mod_python error: "PythonHandler myhandler"
