ASA/PIX 7.x: Redundant or Backup ISP Links Configuration Example

explained very detailed here:
and here:

"Note: The configuration described in this document can not be used for load balancing or load sharing as it is not supported on ASA/PIX . Use this configuration for redundancy or backup purposes only. Outgoing traffic uses the primary ISP and then the secondary ISP, if the primary fails. Failure of the primary ISP causes a temporary disruption of traffic."
