Creating a local custom host name instead of localhost?
In order for the browser to resolve this custom name, you will need to add an alias to your /etc/hosts file. It probably already contains a line about 127.0.0.1, in which case you just add your alias to the list
127.0.0.1 localhost localhost.localdomain myappnameYou can then change the server name in the app's config to make it explicitly use this name.
app.config['SERVER_NAME'] = 'myappname:5000'Only privileged programs (run as root or with sudo) can bind to low ports such as 80, so you will still have to use a high port number.
It can be done using SERVER_NAME option in config:
app = Flask(__name__)app.config['SERVER_NAME'] = 'myappname:80'More information here:http://flask.pocoo.org/docs/0.10/config/
