How to know if a hop link is working?

[asi]

I have 2 products that I'm promoting from CB and when I click the link for one of them, I'm taken to the seller's page but in the URL I see at the end .../?hop=affiliatename. When I click on the hop link of the other product, I do not see my affiliate name at all in the URL. Is this normal and how is my affiliate name stored then if it's not in the URL? Using a cookie or something?
For the previous product that I mentioned, when I click on order now button I'm taken to the ClickBank's order page and I can see my affiliate name on the bottom of the page. However, when I go this other product's sales page and click on the order button, it asks me for my name and email address and I cannot get to the ClickBank's order form at all without entering this information. I am not planning on buying this product so this is why I do not want to enter my information but I also cannot see my affiliate name anywhere on this page. I created the hop links for both products using CB's affiliate link creator that encrypts the URL.
