Authlogic HTTP Basic UserSession.find returns nil, means declarative_authorization can't get a current_user

When using Authlogic's HTTP Basic auth, UserSession.find returns nil since the session appears not to be set. As a result, declarative_authorization, which references the usual current_user method (as below), can't find a current user.

def current_user_session
    return @current_user_session if defined?(@current_user_session)
    @current_user_session = UserSession.find
end

def current_user
    return @current_user if defined?(@current_user)
    @current_user = current_user_session && current_user_session.record
end

Is it possible to create a session when a user auths via HTTP basic (even though that session will only last until the request closes) or is there a better way of doing this?

Having fiddled with Devise, everything now seems to be working, as long as when using ActiveResource I do site = "http://user:password@domain", rather than:

site = "http://domain"
username = "user"
password = "password"

Which doesn't work. I havn't taken the time to dig into why.
