# If you ever try to use Vmchecker on a UserDir-type environment

# It appears that mod_python tries to set a cookie with the path

# gets mangled and the browser doesn't send the cookie back.
#
# This results in the app never logging in, simply coming back

# If you have access to the browser config, you can try and
