What happens on the server at the time of the client's request?

Question

Flask

Hello! I can't sleep for a week because of this question in my head :)
Let's say we have a regular "Hello world" deployed project in Flask. The client asks him this "Hello, world". I'm interested in: how does the Flask code interact directly with the client? An application instance is created or something else ... I still can’t understand, does Flask really work out the same code for 1000 requests per second? Sorry if this question requires psychic abilities, namely telepathy :)

Depends on how the script using
flask is run, if you just run the python script in debug mode from the console,
then depending on the **options arguments, each new request
is served either by a separate thread or process, or just one request at a time.
If the question is about production, then let's say you have nginx + uwsgi and your script,
then uswgi will create how many workers are written in its configuration and they will take turns processing requests that nginx sends using WSGI
