Adaptive Redirection Module

The Adaptive Redirection Module (ARM) provides several essential functions. One is to send device notifications for cluster communication interface failover. Another is to inspect incoming packets before a routing decision is made and redirect the packets to Content Gateway for processing.

The ARM:

• Is always active.
• Uses iptables, policy routing, and transparent sockets which are configured during product installation.

  The installation program also creates redirection rules to intercept packets.

• Supports automatic bypass of sites that do not transit properly through a proxy.
• Prevents client request overloads.

  When there are more client connections than the specified limit, the ARM forwards incoming requests directly to the origin server. See Connection load shedding.
