Good info, but unfortunatly it doesn't seem to help here. The issue here 
is the current payment structures reliance on *different* pages for 
accept and decline.

When the whole process is encapsulated in the handlescript, as it will 
be when the entire bank interaction takes place between my server and 
the banks server in one single transaction.

So there is one http POST from the customer to my server, and in the 
response to that request I process his payment and should be able to 
respond "yes" or "no" to him. Now I can't, because the whole procedure 
is set up for using redirects to the bank and the bank redirecting back 
to the right page.

I could of course hijack Typo3's flow of control in PHP or using 
JavaScript, but then I put myself in danger of T3 updates and changes 
something, and also lose the security and robustness the bank wants me 
to have by not having to use redirects.
