WSGI requires that you have a callable called `application` defined directly
in your *.wsgi file...
In your code, application is just a method of your Handler class, so it's
not going to work at all. Consider using one of these three patterns...
# Pattern 1
def application(environ, start_response):
start_resposne(...)
return [content]
# Pattern 2
class MyApplication:
def __init__(self):
...
def __call__(self, environ, start_response):
start_response(...)
return [content]
application = MyApplication()
# Pattern 3
class application:
def __new__(cls, environ, start_response)
self = object.__new__(cls) # is this right?
content = self.DoSomething(environ)
start_response(...)
return [content]
