Dynamic OAuth Facebook Callback URL?

Question

Is there a way to specify a dynamic callback URL to redirect from Facebook authorization? The Facebook app requires a URL with a slash at the end. What I'm trying to do is add a username or application key so that I can do some dynamic logic on the callback url page. I would like to use the same callback url for many users, so even parameters could help.

As far as I know, you cannot add such parameters as you want.

But in some cases, the parameters are added to facebook (for example, auth_token in OAuth).
