I would like to suggest guys to implement multiple solutions together to meet the redirect need. Letting customers themself to choose from WHERE to go after adding item to cart.
E.g. In the cart page, show
Checkout | Back to Home | Back to Last Category
I have not try but it should be a pretty good idea.
Anyone have this tested please post the final solution here and share to each other. (I m not a php guy so I have no idea to do it myself).
Thanks to all of you who shares here~~
