How to set Access-Control-Max-Age for flask_cors?

Question

In my flask application, I need to set Access-Control-Max-Age. What is the correct syntax for it?

from flask import Flask, send_from_directory
from flask_cors import CORS, cross_origin
app = Flask(__name__,static_folder='./build') 
CORS(app)

Take a look at flask_cors.CORS section, the max_age part.

max_age (timedelta, integer, string or None) –

The maximum time for which this CORS request maybe cached. This value is set as the Access-Control-Max-Age header.

According to the docs, you may need to init your CORS with this parameter.

CORS(app, max_age=3600)
