New Features
HTTP Redirection Enhancements
AOS11.2 allows sending additional information when redirecting to a captive portal. The
additional information available is:


The subscriber MSISDN – available onlywhen working with SMP.



The web address the subscriber tried to access

Using this information allows the portal to automatically detect the identity of the subscriber
accessing it and present him with a custom web page (for example advising him on campaigns
and showing him his account status). In addition it is now possible for the portal to automatically
redirect the subscriber to theoriginal page he wanted to access once the portal activity has
ended.

Classification Enhancements
AOS11.2 improves the classification capabilities of the device and now allows the following
capabilities on top of the existing ones:


Subscriber classification according to XFF field of the HTTP header . This capability
allows classification of traffic to a subscriber based on the IPappearing in the XFF field
instead of the IP of the TCP connection. In non-transparent proxy environments the proxy
establishes the session with its own IP rather than the subscriber IP. If classification of
traffic to the subscriber is done according to the subscriber IP, any traffic flowing through
the proxy will not be classified correctly. In order to associate traffic flowing through theproxy to a subscriber the traffic needs to be classified according to th e XFF field of the
HTTP header that represents the actual subscriber for which the proxy established the
session. Supporting this capability allows operator to deploy subscriber management
capabilities in non-transparent proxy environments, without waving on any of the DPI
capabilities.



Classification of trafficaccording to physical port . This capability allows the operator
to classify traffic to a policy based on the physical port of the device from which the traffic
came from. In many environments this capability can be used in order to differentiate
domestic from international traffic as well as to differentiate traffic coming from different
network elements.
