Caching WebControl

[Jason MacKenzie]

When I use the partialcaching attribute on my custom control (not a user
control) it really doesn't seem to do anything at all and I'm wondering what
the proper way to do ths is? Here is the code I'm trying. I don't have a
clue how to do this so any help would be great. The part enclosed in
asterisks is the first attemo. It didn't throw any exceptions but I would
always get " not cached" in the HTML source.

Thanks for any help,
