Cisco PIX with two internet connections

[GoodCitizenX]

Hi,

I have a situation where I have two internet connections with two seperate ISP's. I would like to configure a PIX firewall to use both of them based on what traffic is been sent out.
Eg: I want to send out on 25 from a mail server and have the pix route it to connection one based on the fact it came from and going to port 25. And I want it to route to connection 2 if it is a web request on port 80.

Sounds simple but I want to verify the Pix can do it before making a purchase

Just read over this post and figured out how silly it reads.

Essentially we are running two PIX firewalls at the moment with a bunch of servers behind them. My company has a requirement to segment the DMZ into trusted and un-trusted.

Diagram of current config:

ISP -> Router -> PIX -\
\_Internal Network
/
ISP -> Router -> PIX -/

Diagram of proposed config:

ISP1 -> Router -> PIX - \-> DMZ-> F/W(PIX?)->Int network.
/
ISP2 -> Router -> PIX -/


Mail needs to go out on ISP1 while

http://www needs

to go out on ISP2.
Hope this clears up my previous rubbish.
