How can you count the number of HTTP requests in an application?

To count the number of HTTP requests in a Python application, you can use several approaches depending on the framework used.

For example, in Flask, you can create a simple middleware or use a decorator to count requests:

from flask import Flask, request

app = Flask(__name__)
request_count = 0

@app.before_request
def count_requests():
    global request_count
    request_count += 1

@app.route('/')
def index():
    return f"Number of requests: {request_count}"

if __name__ == '__main__':
    app.run()

If the application is more complex, you can use specialized monitoring tools, such as Prometheus with a metrics exporter, which automatically collect and visualize the number of requests.

You can also log requests and analyze logs to count them.
