Redirection of domain within <VirtualHost> tag - regex

Question

I have the following in my apache2.conf file for a django project:
#ServerRoot "/etc/apache2"
<VirtualHost *:80>
Alias /static /home/ubuntu/Avails/static
# virtual host configuration
WSGIScriptAlias / home/ubuntu/Avails/wsgi.py
</VirtualHost>
Similar to a previous question I asked here (How to redirect one domain to another).
I have two domains:
www.new.example1.com/ --> IP=1.2.3.4
www.new.example2.com/ --> IP=1.2.3.4 (same IP for both domains)
I want all requests that go to www.example2.com/* to access the requested page. I want all requests that go to www.example1.com/* to redirect to www.example2.com/*. how would I redirect a domain within the VirtualHost block, instead of using the .htaccess file?

Here is what worked. Special thanks to anubhava for the help:
1) Enable module rewrite:
$ sudo a2enmod rewrite
2) Edit apache2.conf file:
<VirtualHost *:80>
Alias /static /home/ubuntu/Avails/static
# virtual host configuration
WSGIScriptAlias / home/ubuntu/Avails/wsgi.py
RewriteEngine On
RewriteCond %{HTTP_HOST} ^new\.example1\.net [NC]
RewriteRule ^ http://new.example2.net%{REQUEST_URI} [NE,R=301,L]
</VirtualHost>
3) Restart apache:
$ sudo service apache2 restart
