post form data to worldpay using c#

[Anthony]

Hi all,

I am just trying to set up a form post to worldppay and finding it
surprisingly difficult.. What i would like is to gather all of the
variables needed in c# codebehind and then send them along to worldpay
along with the user.. Basically i dont want the user to have to submit
a button it will do it automatically..

I have followed this code and i think it posts the data but wont take
the user to the worldpay page as well

Please help as this is really annoying me

Cheers
Anr
