[Moo] Tracking requests made, keeping them around

[Ryan Florence]

I'm about to make a class that
1) Requests data
2) Updates a div
3) Tracks which requests have been made
4) If the request has already been made, then just pull it from  
"memory" instead of requesting it again
5) and therefore, storing the data that was last requested so I can  
pull it from "memory"

Has anybody done something like this that I can take a look at as I  
build this?

Thanks!
