Frequently Asked Questions
What role does wSGI application callable play in WSGI?
Learn wSGI application callable by tracing the example shown in the WSGI lesson. Focus on the problem it solves, what happens at each step, and which result tells you that it worked.
How does environ and start_response fit into WSGI?
Within WSGI, environ and start_response is best understood through use. Recreate the example, inspect the result, and make a small modification so the behavior of the concept becomes clear.
What should I understand about server and application responsibilities when learning WSGI?
In WSGI, server and application responsibilities connects a specific technique to the larger workflow. Work through the lesson example, then change one input or step to see how the result responds.
Why is middleware important in WSGI?
The WSGI lesson uses middleware as a concrete working concept. Reproduce that section yourself and check what changes when you alter the example rather than only reading the explanation.
How is wSGI versus ASGI used when working with WSGI?
For WSGI, the important point is how wSGI versus ASGI works in context. Follow the demonstrated steps, identify the input and output, and note where this concept becomes useful in a real task.
