Thanks for the response. But this is not the answer I was looking for. I am
asking how wsgi is implemented in the nova-api server. How to understand
these python classes ?

How does the flow of control go from one module to another ? Specifically
wsgi related. Is there any design doc which talks about this ? Are there
any resources on the internet along these lines?
