going to www version of site url receives 404 on django site - django

Question

I can get to the route of my site without issues like this: http://example.com
When I go to http://www.example.com I get a 404 error.
How can I handle going to www and delivering the user to the route of the site?
I don't think it is related, but here is my httpd.conf:
WSGISocketPrefix /var/run/wsgi
<VirtualHost *:80>
WSGIDaemonProcess example.com display-name=%{GROUP}
WSGIProcessGroup example.com
ServerName example.com
ServerAlias www.example.com
DocumentRoot /example
WSGIScriptAlias / /example/wsgi.py
</VirtualHost>
Alias /static/ /example
<Directory /example>
Order deny,allow
Allow from all
</Directory>
WSGIPythonPath /example
<Directory /example>
<Files wsgi.py>
Order deny,allow
Allow from all
</Files>
</Directory>

Answer 1

Change ALLOWED_HOSTS in the settings.py to something like this
ALLOWED_HOSTS = ['www.example.com', 'example.com']
According to Django Documentation, ALLOWED_HOSTS defines
A list of strings representing the host/domain names that this Django site can serve. This is a security measure to prevent an attacker from poisoning caches and triggering password reset emails with links to malicious hosts by submitting requests with a fake HTTP Host header, which is possible even under many seemingly-safe web server configurations.
