App Urls

Django loads that Python module and looks for the
variable urlpatterns. This should be a Python list
of django.conf.urls.url() instances.

Django runs through each URL pattern, in order, and
stops at the first one that matches the requested URL.

Each regular expression in a urlpatterns is compiled
thefirst time it’s accessed. This makes the system
blazingly fast.
