or is inactive but module is preceded by an exclamation point (!).

Main Server, Virtual Hosts, and Containers

In order to respond to requests, Apache must listen to a net-

work port. Apache can listen on multiple IP addresses and

ports and can be configured to respond differently according

to the IP address and port the client connected to.

A single IP address may be represented by many different

hostnames. In this case, the hostname requested can be deter-

mined only by examining the

Host HTTP header, which is

new for HTTP 1.1. Note that name-based virtual hosts do not

work with SSL/TLS connections, as the hostname is needed to

set up the secure connection but can only be extracted from

the headers once the key exchange has occurred.

Ports and IP addresses

The following directives tell Apache on which IP addresses

and ports it should listen.

BindAddress

BindAddress{*|IP-addr|fqdn }
