Generally you shouldn't need to worry about this, because connection pooling will take care of it automatically. Just make sure to close your connections when you're done with them (best is to use the using {} block in your code, which will automatically close and dispose your connection).

If you really need to work off the same connection object for some reason, why not have all your controllers inherit from a base controller that exposes your connection object as a property?
