sharing data between custom controls

[axis]

I have two custom controls on a page that work on the same object that needs
some prepping when first loaded. Currently I just load them in both controls
individually, essentially doing the same work twice.

What's the best way to share data between controls? I know I could place the
data in HttpContext, but would I essentially be tripling the amount of
memory I'm using? 1 copy in control1, 1 copy in context, and 1 copy in
control2. Unless context works by reference. Otherwise, is there a better
way? The controls inherit from a common class already -- is there any way to
have a variable in that parent class that is shared within a page?

Thanks

BTW -- there's no need to persist the data after the page is rendered. Sorry
I didn't clarify this. It's just data used while rendering the controls. The
data is needed by various controls.

Create the object at the page level and pass it to both controls.
