appropriate links to the Listen directive. If I had known that so many files had the Port directive in it, I would have bundled this up as one big commit. *sigh* I just kept looking and finding new files, fixing, and committing. So, this should be the rest of them for now. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@91571 13f79535-47bb-0310-9956-ffa450edef68

<h1 align="CENTER">Setting which addresses and ports Apache
|
|
uses</h1>
|
|
|
|
<p>When Apache starts, it connects to some port and address on
|
|
the local machine and waits for incoming requests. By default,
|
|
it listens to all addresses on the machine. However, it needs to
|
|
be told to listen to specific ports, or to listen to only selected
|
|
addresses, or a combination. This is often combined with the
|
|
Virtual Host feature which determines how Apache responds to
|
|
different IP addresses, hostnames and ports.</p>
|
|
|
|
<p>The <code>Listen</code> directive tells the server to accept
|
|
incoming requests only on the specified port or
|
|
address-and-port combinations. If only a port number is
|
|
specified in the <code>Listen</code> directive, the server
|
|
listens to the given port on all interfaces. If an IP address
|
|
is given as well as a port, the server will listen on the given
|
|
port and interface. Multiple Listen directives may be used to
|
|
specify a number of addresses and ports to listen to. The
|
|
server will respond to requests from any of the listed
|
|
addresses and ports.</p>
|
|
|
|
<p>For example, to make the server accept connections on both
|
|
port 80 and port 8000, use:</p>
|
|
<pre>
|
|
Listen 80
|
|
Listen 8000
|
|
</pre>
|
|
To make the server accept connections on two specified
|
|
interfaces and port numbers, use
|
|
<pre>
|
|
Listen 192.170.2.1:80
|
|
Listen 192.170.2.5:8000
|
|
</pre>
|
|
|
|
<h2>How this works with Virtual Hosts</h2>
|
|
|
|
<p>Listen does not implement Virtual Hosts. It only tells the
|
|
main server what addresses and ports to listen to. If no
|
|
<VirtualHost> directives are used, the server will behave
|
|
the same for all accepted requests. However,
|
|
<VirtualHost> can be used to specify a different behavior
|
|
for one or more of the addresses and ports. To implement a
|
|
VirtualHost, the server must first be told to listen to the
|
|
address and port to be used. Then a <VirtualHost> section
|
|
should be created for a specified address and port to set the
|
|
behavior of this virtual host. Note that if the
|
|
<VirtualHost> is set for an address and port that the
|
|
server is not listening to, it cannot be accessed.</p>
