Try to attach the second url to the same view as the third url use something like this.
url(r"^$",my_project.views.user_login, name="home")
Another approach would be.
from django.core.urlresolvers import reverse_lazy
from django.views.generic import RedirectView
urlpatterns = patterns('',
url(r'^/$', RedirectView.as_view(url=reverse_lazy('home'))),
Does this work??
