If you need to "refresh" the 2nd select list, I think the best way is using
frameset to submit a hidden page to the server, get back the new values and
repopulate the orignal page by client side javascript. Like this you won't
have to each time unload the page, you don't need to reload the 1st list.

Depends your needs
