CIM hosted form return-url: How to know which button clicked?

[wbr]

I'm using the return-url of the CIM hosted payment form to make intelligent navigation & processing decisions after the user "leaves" the hosted form. But I can't figure out how to determine which button the user clicked. Can the return-url insert any information about the environment of the hosted form, before it is sent to the browser? There is a HUGE difference between "Continue" and "Cancel", yet there is no way to know which of these was clicked.

Any hidden techniques, workarounds, or obvious features I've missed?

Thanks,

Bill

Hi Bill,

The iFramecommunicator is used to relay the actions to your page. You can see an example of this communicator page in the sample code.
