72: =head1 SYNOPSIS
73:
74: The way this is supposed to work:
75:
76: User A has client machine C
77: User A is logged into LON-CAPA server S
78: needs file from user B
79: homeserver for user B is H
80:
81: This is part of the LearningOnline Network with CAPA project
82: described at http://www.lon-capa.org.
83:
84: =head1 HANDLER SUBROUTINE
85:
86: This handler runs on H
87: To access a userfile:
88: Server S generates a token and puts it into the query string of URL for H
89: Client box C asks H for file with token issued by C
90: H now must ask S if token is valid, uses S's lond-command tokenauthuserfile
