Dual Concurrent T1 Cisco Router Configuration Template

I have a client that has a Cisco 1841 Router with a single T1 connected to it.  It runs everything from NAT's to VPNs.  

They are getting a second T1 to do a special type of configuration that I know for a fact can be done (just not sure how).

They want the new T1 to only be used for http,https and ftp outbound traffic.  All other traffic, NATS and VPNS will still be on the old T1.

They also have a 2nd WIC and Ethernet port installed.

What I need is just a template or ideas on what type of configuration would be needed.  I am doing this Thursday June 26th so any help would be awesome!!!!!!

Please let me know if any further information is needed.

Policy based routing should be the answer
try doing something like the below i guess this should do the trick just hope it doesnt block other traffic :) so test it in off business hours :)

Router(config)#int fa0/0   <<< your LAN interface
Router(config-if)#ip policy route-map MATCH_INTERNET

Router(config-if)#route-map MATCH_INTERNET
Router(config-route-map)#match ip address MATCH_INTERNET
Router(config-route-map)#set ip next-hop 50.50.50.50    <<< The remote end of the new T1

Router(config)#ip access-list extended MATCH_INTERNET
Router(config-ext-nacl)#permit tcp any any eq 80
Router(config-ext-nacl)#permit tcp any any eq 8080
Router(config-ext-nacl)#permit tcp any any eq 443
Router(config-ext-nacl)#permit tcp any any eq 21
Router(config-ext-nacl)#permit tcp any any eq 20

Logic2,
Thanks for the quick reply.

That seems to be very logical.  I have never used a policy based config.  

Just to make sure I understand it correctly....
Router(config-route-map)#set ip next-hop 50.50.50.50    <<< The remote end of the new T1
Are you talking about the T1 gateway?

Thanks

mmm not sure but let me explain

my router with ip x.x.x.x -------------- T1 -------------- Service Provider with ip y.y.y.y
so in our case the next hop would be the y.y.y.y
