-The default Apache settings in the /etc/default/apache2 configuration file relate to local caching, using the mod_disk_cache module

-You can activate the module with the following command:
$ sudo a2enmod disk_cache

-Global settings for the Apache web server are configured by default in the /etc/apache2
/apache2.conf configuration file

3.Examine the First Host

-The first host is configured in the /etc/apache2/sites-enabled/ directory, in the 000-
default configuration file. It’s a virtual host, linked to the file named default, in the /etc/
apache2/sites-available/ directory

For example, suppose that you are serving the domain www.domain.tld and you wish to add the virtual host www.otherdomain.tld, which points at the same IP address.

NameVirtualHost *:80

VirtualHost *:80
ServerName www.domain.tld
ServerAlias domain.tld *.domain.tld
DocumentRoot /www/domain
/VirtualHost

VirtualHost *:80
ServerName www.otherdomain.tld
DocumentRoot /www/otherdomain
/VirtualHost

$ sudo cp 000-default website1
