Cisoc ASA QoS

I have 2 ASA version 7.2 with L2L IPSec VPN tunnel configured (5 Mbps of
internet bandwidth).

I need to configure qos only across this Lan to Lan IPSec tunnel (5 Mbps
total bandwidth) with a Rate limit policy: in particular I need to configure
for this tunnel a policy that set 2 Mbps for the http traffic, 1 Mpbs for
the https and 500 kbps for all the other traffic on the L2L IPSec)

ANY Configuration Example on this would be greatly appreciate.
