Sequence for Redirecting Traffic

The sample IDP captive portal takes the following actions in response to incidents detected by IDP:

1. The portal’s record servlet records HTTP messages that it receives from the IDP management server. The messages include the source and destination IP addresses of problem traffic and a problem description.
2. The IDP management server activates a service that policy-routes the subscriber's Web traffic to the redirect server.
3. When the subscriber tries to access the Web, the redirect server responds to the subscriber's Web traffic by redirecting the subscriber to the IDP captive portal through an HTTP redirect process.
4. The IDP captive portal then retrieves the subscriber’s IP address and the stored messages for this IP address, and displays messages appropriate to the subscriber.
