HTTP Redirect Using PBR
The HTTP Redirect (HTTPR) feature is used to redirect subscriber traffic to a destination other than the one
to which it was originally destined. The HTTPR feature is implemented using Policy Based Routing (PBR)
that makes packet forwarding decisions based on the policy configuration, instead of routing protocols. The
HTTPR feature is implemented by sending an HTTP redirect response, which contains the redirect URL, back
to the HTTP client that originally sent the request. Thereafter, the HTTP client sends requests to the redirected
URL. HTTPR is supported for IPv4 subscribers.
The most common use of HTTPR feature is for initial logon. In some cases, it is not possible to uniquely
identify a subscriber and authorize them. This happens when the subscriber is using a shared network access
medium to connect to the network. In such cases, the subscriber is allowed to access the network but restricted
to what is known as an "open-garden". An open-garden is a collection of network resources that subscribers
