Forcing Android to not redraw activity on orientation change

Question

I have been going gaga to figure this out.
Although I have read a lot that on Orientation Change, Android kills an activity and starts it as a fresh one, and the only way to handle this is to save all the stuff inside onSaveInstanceState() and try to restore it inside onCreate().

But my activity does a lot and different kind of network activities at different times and if the orientation is changed when the network activity is being performed, I'll have to handle a lot of different and complex scenarios.

Is there any simple way to just point Android that this activity doesn't need to be redrawn at all when the orientation is changed so that it automatically saves all the data and re-uses it?

I wonder if there's any thing like that.
