Facebook Queries - How to Pass Custom Variables from the Queries Page

Question

I am creating a facebook application that has the function of sending to friends.

Each user is provided with a specific user key that identifies them and themselves.

So Person A invites person B.

So, when person B receives an invitation, when they click ACCEPT, we pass the referrer user link to the URL ... for example http://mydomain.com.au/return_user.aspx?referrerkey=iuahsduiahsdfuiha

So, when person B has already installed the fb application, referrerkey variables are transferred back to our website, so we can manage the link between the two users.

However, if person B has not added the application. And Person B presses the ACCEPT button on the invitation page, which the user must take on the "Allow access" page, from there they return to the APP home page, and I do not need any of the variables. For instance. key link.

So, how can I make this work for both users who have already added the application and havent added the application?
