I don't have a readymade sample, but here is the logic:
ACL 120 is for http traffic
ACL 180 is for ftp traffic
Define 2 ipsec transform sets with name httpset and ftpset (for example),
Define 2 crypto maps with different sequence numbers
Under crypto map httpmap, specify match address 120 and httpset
under crypto map ftpmap, specify match address 180 and ftpset
apply the crypto map to the interface.
hope this helps,
Vijay
