Assistance please !!!

I am currently working on an order entry program which requires the ability to validate credit cards via the internet.

We are already working with a credit card service bureau that provides a site where we can enter the credit card number and have it validated immediately.

We've purchased WWC to do this and I've found it to be more than capable!

But, I still have a question...

We don't have access to a "test" site on the internet for use during development, so I created one using (what else?) WWC. This site takes a credit card number and returns a validation code, just like the *real* site will.

What I need to do now is have my order entry program call the *test* site just as it will call the *real* site in production.

The problem is, I don't know what web "address" to use in the call to HTTPConnect(). I've tried "localhost" and several others but I continually get timeout or bad url errors.

So the question is... what's the address I should you to connect to an intranet site on the same PC using HTTPConnect()?

I'm running NT4 with Peer Web Server.

TIA
