20 * \file
21 * Implementation of Cookie Management
22 *
23 * This allows users to view and remove their web cookies.
24 *
25 * \todo the viewing of cookies is pretty basic and it would be good
26 * to apply more processing of the values and perhaps top level domain
27 * suffix highlighting to give a better user information as to how the
28 * cookies interact with the users sessions.
29 *
30 * \todo In addition to removing cookies it might be useful to allow
31 * users to edit them, especially to alter expiry times.
