no.

i have 2 physical asa5520. we are thingking of creating 2 context on each asa and configure the ff

asa1

context A - active

context B - passive

asa2

context A - passive

context B - active

thereby we will be having 2 asa's with diff ip address on the outside.

we want the traffic comming in to our web servers to be load balance bet this 2 asa's

thanks

Yes that is possible,In order to run active/active mode you have to be running

multiple context mode on your PIX.

but do i need a firewall load balancer on the outside to achieve this?

note that i now have 2 diff ip address on both the active context. how will my single outside router know to which firewall it will throw the traffic?

thanks

Im not quiet convinced that active/active was really designed for load balancing in the way you are trying to achieve in on the ASA. To answer your question I would think you will need some form of external\internal load balancer, im my experience the ASA will not do what you trying in a nice clean manner all by itself.
