Hello

I am experiencing a rather strange problem with an eCom solution. Here is some info about the DW our customer is using:

DW
Content version:     18.16.1.13 (Updates.xml)
Assembly versions:     Dynamicweb.dll 18.16.3.2
(File version: 18.16.3.2 Dynamicweb, Version=18.9.1.1, Culture=neutral, PublicKeyToken=null)
Dynamicweb.Admin.dll 18.16.3.2
(File version: Dynamicweb.Admin, Version=18.9.1.1, Culture=neutral, PublicKeyToken=null)
Dynamicweb.Controls.dll 18.16.3.2
(File version: Dynamicweb.Controls, Version=18.9.1.1, Culture=neutral, PublicKeyToken=null)

It is an old DW. I know. We have developed a custom gateway provider, to RBS. It is not supported by DW by default.

The problem is like this:
1. a user logs on the webshop
2. the user picks som goods
3. the user is sent to the gateway
4. the user fills the form
5. the user is sent back to the shop where an order is sent to the shop and a confirmation is sent to the user

For the most of the time, the user is sent back to the shop, but instead of a "thanks for your ordre" page, the user is shown a login page. Here the user does not receive a
order confirmation, nor do the shop receive the order, but the order is auth'ed in the RBS system. This has happend for alot of user. Mostly 95%, but the last 5% is sent through.

This url is the one handing over the the user from the shop to the RBS system: https://secure.worldpay.com/sc2/jsp/shopper/SelectPaymentMethod.jsp?OrderKey=DKRCPET%5EORDERs22048&successURL=http%3A%2F%2Froyalcanin.dk%2FDefault.aspx%3FID%3D170%26step=5%26order%3Dcomplete

telling the RBS system, to send the user back to http%3A%2F%2Froyalcanin.dk%2FDefault.aspx%3FID%3D170%26step=5%26order%3Dcomplete on success. I have for 2 days straight tried to regenerate the problem, and it have only succedded me
2 times. But then the returning URL is different: http://royalcanin.dk?ID=170&step=5&order=complete&orderkey=MARSCHOCO^DKRCPET^ORDERs21999&paymentStatus=AUTHORISED&paymentAmount=10500&paymentCurrency=DKK&mac=2707fdab769695276be660c195bcf5c6&jlbz=EZqDpGi0omlr052sPNemm6og0pxPKyg8RQkHsSrg
 
It has alot of extra parameters. And I am suspecting that this URL is what 95% of the users is getting. It sends the users to a login screen.
My question is therefore: Can the returning url be the sinner?
When I was retuned to the shop with this URL, I did not wait a long time on the RBS side. It took at most 1 minute. This I have replicated on a virtual box, with FF 5 and XP Proffessional.

I do not know what to do know. Hope there is someone out there who can help me.

An upgrade of the DW is not a solution for now. Because the customer has some failing custom modules attached to it that need to be handled first. But they want to use RBS right away.
