Best practice approach to caching dropdown values

[oj]

Could anyone provide some approaches that are used to cache dropdown
list control values to share globally beteween all users? Currently,
each time a page is loaded all the dropdown values for each dropdown
list control are retrieved from the database. I would like to go away
from this approach. Any info. is appreciated.

Create a data container to hold the data.
A Dataset, a BusinessObject Class, an Arraylist, etc.

Then store the container in cache.
Expire the cache every X minutes and re-load it from DB.

There is a way to use DB cacheinvalidation in ASP.Net 1.1 but it is tricky.
Just get it working first.
