Load Balancer Cross-port affinity


Cross-port affinity is the sticky feature that has been expanded to cover multiple ports. For example, if a client request is first received on one port and the next request is received on another port, cross port affinity allows Dispatcher to send the client requests to the same server.

For example, a user browses products and adds them to his shopping cart using port 80 (HTTP). For viewing the shopping cart and for the checkout process, HTTPS is used, which will encrypt all communication between the browser and the server. Cross-port affinity enables Dispatcher to forward this user's requests for both ports 80 and 443 to the same server.

In order to use this feature, the ports must:

More than one port can link to the same cross port. When subsequent connections come in from the same client on the same port or a shared port, the same server will be accessed.

Cross-port affinity applies to the MAC and NAT forwarding methods of the Dispatcher component.

Note: The same drawbacks apply as for source IP affinity (see above).
