36: # needs file from user B
37: # homeserver for user B is 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
