Intended URL redirect + default redirect after login?

[pixel6867]

When a user tries to access our website via a link (for instance going to www.website.com/privatepage) they are redirected to a login page. Once they login, we want to redirect them to that intended URL - how do you do this?Also we have a use case where a user logs in from the homepage, or goes directly to the login page with no intended URL - in this case we'd like to redirect them to a default page.Can anyone help me figure this out?Technology: Codeigniter, jQueryThanks,Walker
