does asa version 8 support secindary ip? Policy based routing?

Hi Experts,

my topology is this something like;

ASA 5520 -----|Outside VLAN| -----R1----| ISP1

                                          | -----R2----| ISP2

Proxy appliance is NAT'd on ASA, NAT is only for one ISP IP .. If that ISP goes down internet goes down for users accessing internet through that ISP.

What I saw in documentation, ASA limitaiton: No policy based routing, No secondary IP. Is there any work arround except static ARP entry?

What i think is, I should exempt NAT for proxy IP and let routers ISP1 & ISP2 do NAT. Both Rotuers will have NAT'ing statements. Using HSRP I can force ASA to forward proxy traffic to Active router (that has internet reachability tracked by HSRP).

Any suggestions?

Regards

Mudasir Abbas
