integrating ibill into the opensrs scripts

[lp]

Hello,   I'd like to talk with webmasters who are using iBill (www.ibill.com) to accept credit cards, and have integrated it with the OpenSRS cgi scripts. I've tried to do it, but I can't. See, when a user does a whois on a domain, and it's available, they will be given the option to register. I want to take them to the iBill payment page after that. When they have paid, they'll see the thank-you page, which contains the registration form.   Two problems here: 1) You can't pass any variables to the thankyou page, so the user can pick ANY domain after paying, including already registered domain names. 2) They can order a domain, verify the order and all, and when it's done, click <back> a couple of times and go through it again, without going to the iBill payment page ('hello page').   Any suggestions?   Thanks a lot,   Laurens Pilger
