title: Redirect if already logged in through Django urls?
body: <p>Currently I use these patterns to log in and out</p>
  
  <pre><code>urlpatterns += patterns("",
      (r'^login/$', 'django.contrib.auth.views.login', {'template_name': 'login.html'}),
      (r'^logout/$', 'django.contrib.auth.views.logout', {'template_name': 'logout.html'})
  )
  </code></pre>
  
  <p>Inspite of having LOGIN_REDIRECT_URL = '/profile/' in my settings.py, Django does not send me to /profile/ if I want to access /login/ when I'm already logged in...</p>
  
  <p>Can I somehow redirect in the URL patterns of the auth system? I'm reluctant to write a custom view for that.</p>
