There is a problem with call back faeture in this contribution.
If you cancel a payment, you are redirected back to the store to either chose another payment method or try again.
The callback feature returns you to a checkout called in http and not https.
I need someone to fix this so it is called in http.
This should be easy job for someone, one file to work on.
