This version of captiveportal.inc has been modified by Rob Parker
|
|
34
|
<rob.parker@keycom.co.uk> to include changes for per-user bandwidth management
|
|
35
|
via returned RADIUS attributes. This page has been modified to delete any
|
|
36
|
added rules which may have been created by other per-user code (index.php, etc).
