Is winhttp the correct solution??? wondering how....

[yukeshean]

hi,
I'm helping a company to develop a merchant site for online transaction.
Since the company already registered with Telemoney payment gateway to
handle the credit card verification, therefore my asp pages will need be
devloped to talk to the telemoney server in order to pass and receive data
like credit card no, transacted amount etc.
Initially i thought that applying asp form method will be fine to submit
data over to their server, but found out actually not. This is becoz I need
to establish a https connection to their server first before sending any
data.
Is winhttp the correct approach?
There is few communication links in one transaction and it need to have 3
asp pages involved.
First submit a new request into the server, after that the server will
establish another new connection to a new asp page (so-called payment url)
and from this page, i shall send the transaction information to the server
etc, and at the last portion (status acknowledgement), the payment gateway
server will send status information to another asp page (status page). At
the page, I shall capture the status information and reply with an
acknowledgement.
How can it be done with asp? Use winhttp? how......
Please do advise...

Thanks and Regards, yukeshean

I've dealt with such things with web banking systems, and the web banking
vendor offered a "pre-fetch" image that I could load. Even if this isn't
provided, you can do it with an image, or even by 404ing to their site.
Just add something like this on your page:

<img src=https://www.theirsite.com/images/something.gif width="0" height="0"

I may have lied. I just looked at one of the web banking pages I did, and
the img src is an actual coded page. It's like this:

<img
src="https://www.ourwebbankingprovider.com/relevantsubdomain/beforelogin.cfm
" width="0" height="0">

(damn cold fusion. pffft)
