Passing in args from a link in email

I have a registration form that constructs a link and emails it to the user. The user clicks the link to confirm their new account. How do I get the parameters into the app (in a session) so I can display the login page, dialogs, etc. In short, interact with the user?

Example link format:

I need to get the vars action, email, and code into the web app and display a dialog to the user that their account is now active and then redirect them to the login page.

Sorry if this has already been covered. I don’t have the first clue of what to search for in the forums.

Use the Session.URLParameter methods.

That’s right. I knew I had done something with it before but couldn’t remember where I placed the code or what I was looking for.

Thanx Tim!
