# Demonstrates use of the auth and put handlers to support publishing
# web pages via HTTP.

# It is also possible to set up the ftp server to do essentially the
# same thing.

# Security Note: Using HTTP with the 'Basic' authentication scheme is
# only slightly more secure than using FTP: both techniques involve
# sending a unencrypted password of the network (http basic auth
# base64-encodes the username and password).  The 'Digest' scheme is
# much more secure, but not widely supported yet. <sigh>

# For this demo, we'll just use a dictionary of usernames/passwords.
# You can of course use anything that supports the mapping interface,
# and it would be pretty easy to set this up to use the crypt module
# on unix.
