Redirect and pass as a parameter the original url from an Interceptor

[Alfredo Manuel Osorio Martinez]

I am implementing a Login interceptor which needs to redirect to an
action to first authenticate the user. The problem is that I want to
send as a parameter to that action the original url, the one that the
user was trying to get before the redirect to the login page.

 

How can I achieve that?

 

Thanks in advance,
