What is BitTorrent ?

BitTorrent is a leading Peer 2 Peer file distribution protocol. It is a network system for the download of movies, software, music and other large files over the Internet. It’s peer 2 peer nature enables users to connect to each other directly to send and receive portions of the file. There is a tracker which coordinates the action of all such peers. The ideology of BitTorrent is that users should upload (transmit outbound) at the same time they are downloading (receiving inbound.) which ensures that the network bandwidth is utilized as efficiently as possible.

The BitTorrent network is designed to support simultaneous upload and download involving many people, also referred to as “swarms.” Its efficient network bandwidth utilization makes BitTorrent an ideal choice for those looking to download a large movie file, music file, or open software package that is currently being shared on the Internet.

Apache : Name Based Virtual Hosts

The notable difference between IP-based and name-based virtual host configuration is the NameVirtualHost directive which specifies an IP address that should be used as a target for name-based virtual hosts.

For example, we use both http://www.abc.com and http://www.xyz.com at the IP address 192.168.0.1 We simply add to one of the Apache configuration files:

NameVirtualHost 192.168.0.1
192.168.0.1>
ServerName http://www.abc.com
DocumentRoot /www/abc

192.168.0.1>
ServerName http://www.xyz.com
DocumentRoot /www/xyz

Of course, to make this work, all that is needed is to make sure that the names http://www.abc.com and http://www.xyz.com are pointing to the IP address 192.168.0.1
