How do I run multiple python apps in 1 command line under 1 WSGI app?

This document discusses running multiple Python web applications under a single WSGI server. It presents a Flask "Hello World" app and a Django "Hello World" app that run on different ports. It then shows how to use a WSGI dispatcher middleware to combine the two apps so they run on the same port from a single command line. Sample code is provided to demonstrate configuring WSGI to dispatch requests between the Flask and Django apps.
![THIS IS A HELLO WORLD DJANGO APP
from django.http import HttpResponse
def hello(request, name):
return HttpResponse("<p>Hello, %s I'm a Django app.</p>" % (name,))
views.py
from django.conf.urls import patterns, include, url
urlpatterns = patterns('',
url(r'^(?P<name>[-w]+)/$', 'hello_django.mysite.myapp.views.hello'),
)
