[TYPO3-shop] Passing back session to tt_products and more

[Franz Holzinger]

Hello Simon Justesen,

No, the gateway only get the backURL to come back. No other parameters 
are passed to it. All data has been stored in the basket at the session 
level.
Use the FE_SESSION_KEY paramter to pass the session id.
I do not know if the session can be retrieved even without it. It would 
be fine if you could test it.

Use the template subparts for your payment choice.

<!-- ###MESSAGE_PAYMENT_40### begin Message for payment method 40, 
Paypal -->
