# The way this is supposed to work:
#
# User A has client machine C
# User A is logged into LON-CAPA server S
# needs file from user B
# homeserver for user B is H
#
# This handler runs on H
# To access a userfile:
# Server S generates a token and puts it into the query string of URL for H
# Client box C asks H for file with token issued by C
# H now must ask S if token is valid, uses S's lond-command tokenauthuserfile
