33: #
34: # User A has client machine C
35: # User A is logged into LON-CAPA server S
36: # needs file from user B
37: # homeserver for user B is H
38: #
39: # This handler runs on H
40: # To access a userfile:
41: # Server S generates a token and puts it into the query string of URL for H
42: # Client box C asks H for file with token issued by C
43: # H now must ask S if token is valid, uses S's lond-command tokenauthuserfile
