ASA and UDP

Can someone answer how ASA creates "state" with UDP traffic? I have seen the matrix document of the approved UDP services, but I would like a better understanding of what makes it work.

TIA

Re: ASA and UDP

It keeps track of what goes out, and to whom (source and destination ports and ip addresses). If replies come back in the alloted time (i think the default udp timeout is 90 seconds, but don't hold me to it), they are let in. Inbound udp packets for which there is no associated outbound stateful entry are dropped.
