Is there a way to get parameters or attributes from the SAML response depending on parameters sent in the request?

In our case we send a forceAuthN request within the application for a secure area. This request is sent to the same configuration as the general login. The difference we have in this case is the redirection after the successful login. We need to know in out application side SAML listener whether the response came from a general login request or the forceAuthN request. It doesn't matter whether we should provide different destination URLs for the response or retrieving parameters or attributes from it.
