ASP.N ET - Losing session when going to Payment Portal

yop

Hoping someone can assist on this one.

Site is ASP.NET and when the user logs in we authenticate them and this is stored within the session while the user is making the booking.
On each page we ensure the user is authenticated in the page load. Works fine so far.

Problem hit now in that we are using Barclays payments for the transactions.
You have an "allowed URL", which is the webpage you are coming from, it its the "payment.aspx" page. That works fine as it then pops up the Barclays page and you enter your details, CC, address etc.
When you are complete you hit the "Process Payment" button on the Barclays site it sends to back to your website ( you have to provide URL as part of the setup of the site.)

This is where the problem is now for me and I can't seem to get a resolution to it. We we are returned from Barclays, even though it returns back to our website, it is returning an error and telling us that the "Return URL failed".
The detail of the error is that its showing that instead of successfully returning to this URL:
"http://13.13.18.13/bookings/cashtransactionff.aspx"
what happening is that its going to this URL:
"http://13.13.18.13/login.aspx?ReturnUrl=/bookings/cashtransactionff.aspx"

From my understanding its like its coming back to the site "fresh" and trying to access that page, where in fact it should be returning to the already "opened" site.

I hope this makes sense!

Any thoughts?

Have you debugged the session state and incoming request cookie values?

Thanks for the reply.
I can't debug it within VS as when I run the site its a "localhost" address and the payment gateway doesn't recognise it on the return URL.

I have tried to attach to the process to debug but its not picking up any of the breakpoints!

I am probably missing something there with that though?

Are you in debug mode or release?

Should your return url not be

http://13.13.18.13/bookings/cashtransactionff.aspx

or something like that.

I remember a few years ago having something similar and I think I pass in the details that I need about the user onto the payment page e.g. Name and address as session values where been lost between my site and payment site.

Sorry yes that is the return URL, typo in my original.
for some reason when it comes back to that page it seems to think the user is not logged in and its throwing them back to the login page.

Very frustrating.

amen

solution for that is you get asp.net to write to a log file (txt file) recording what you need to know.


When you go to Barclays do you not pass user/session info to Barclays and then get them to pass the data back to you. Once you have it back you just revalidate your user.

I'm sure its a type but if you processing orders I assume you are using https and not http ?

Trampas

you will need to assume the user is still logged in on the initial return.

you pass the require info you need in the return to the payment page.

this information should be in a it's own tag on the xml with authcode or payres

i can have a look tomorrow when back in work as it was a few years ago since i did it
