Authlogic Oauth problem with Remember Me

My sole login type is Twitter OAuth; I'm using Authlogic with the Oauth addition for authentication. I'm trying to build my Rails app such that the user is automatically redirected to Twitter's login/registration, instead of having a "login with Twitter" button on my page.

That works so far, using a new view like this:

<html> <body> <% form_tag(user_session_path, :method => :post, :id => 'new_user_session') do %> <%= hidden_field_tag 'login_with_oauth', 'Login with Twitter' %> <% end %> <script type="text/javascript"> var e = document.getElementById("new_user_session"); e.submit(); </script> </body> </html>

I'm trying to get Remember Me to work now, without success. I added this line:

<%= hidden_field_tag 'user_session[remember_me]', '1' %>

to the above form, but that doesn't appear to work; I still get redirected to Twitter (after restarting the browser).

I'd like to be able to get Remember Me behavior out of the registration, too, if that's possible. So the user goes to the app, registers, and ~never signs in again.

Any ideas what I'm missing?

Thanks, Andrew
