The new features in this release are:
- Content Based Routing (CBR) component
- Content based routing provides the ability to balance the load
based on the content of the client requests, such as URI.
- Site Selector component
- Site Selector provides the ability to balance the load on servers
within a local or wide area network using a DNS round-robin approach
or a more advanced user-specified approach. Site Selector works in
conjunction with a name server to map DNS names to IP addresses.
- Using NAT forwarding to forward traffic
- Using Network Address Translation (NAT) Dispatcher capability
removes the limitation for the backend servers to be located on a
locally attached network.
- Configuring collocated servers for the Dispatcher component
- Load Balancer can reside on the same machine as a server for which
it is load balancing requests. This is commonly referred to as collocating
a server. It is supported on Linux and AIX only.
