Why do I need WSGI?

How does a WSGI server work?

Purpose. WSGI stands for “Web Server Gateway Interface”. It is used to forward requests from a web server (such as Apache or NGINX) to a backend Python web application or framework. From there, responses are then passed back to the webserver to reply to the requestor.
