-<h2><a name="purename" id="purename">Running several name-based web
- sites on a single IP address.</a></h2>
-
- <p>Your server has a single IP address, and multiple aliases (CNAMES)
- point to this machine in DNS. You want to run a web server for
- <code>www.example1.com</code> and <code>www.example2.org</code> on this
- machine.</p>
-
- <div class="note"><h3>Note</h3><p>Creating virtual
- host configurations on your Apache server does not magically
- cause DNS entries to be created for those host names. You
- <em>must</em> have the names in DNS, resolving to your IP
- address, or nobody else will be able to see your web site. You
- can put entries in your <code>hosts</code> file for local
- testing, but that will work only from the machine with those
- hosts entries.</p>
- </div>
-
- <div class="example"><h3>Server configuration</h3><p><code>
-
-
- # Ensure that Apache listens on port 80<br />
- Listen 80<br />
- <br />
- # Listen for virtual host requests on all IP addresses<br />
- NameVirtualHost *:80<br />
- <br />
- &lt;VirtualHost *:80&gt;<br />
- <span class="indent">
- DocumentRoot /www/example1<br />
- ServerName www.example1.com<br />
- <br />
- # Other directives here<br />
- <br />
- </span>
- &lt;/VirtualHost&gt;<br />
- <br />
- &lt;VirtualHost *:80&gt;<br />
- <span class="indent">
- DocumentRoot /www/example2<br />
- ServerName www.example2.org<br />
- <br />
- # Other directives here<br />
- <br />
- </span>
- &lt;/VirtualHost&gt;
- </code></p></div>
-
- <p>The asterisks match all addresses, so the main server serves no
- requests. Due to the fact that <code>www.example1.com</code> is first
- in the configuration file, it has the highest priority and can be seen
- as the <cite>default</cite> or <cite>primary</cite> server. That means
- that if a request is received that does not match one of the specified
- <code>ServerName</code> directives, it will be served by this first
- <code>VirtualHost</code>.</p>
-
- <div class="note">
- <h3>Note</h3>
-
- <p>You can, if you wish, replace <code>*</code> with the actual
- IP address of the system. In that case, the argument to
- <code>VirtualHost</code> <em>must</em> match the argument to
- <code>NameVirtualHost</code>:</p>
-
- <div class="example"><p><code>
- NameVirtualHost 172.20.30.40<br />
- <br />
- &lt;VirtualHost 172.20.30.40&gt;<br />
- # etc ...
- </code></p></div>
-
- <p>However, it is additionally useful to use <code>*</code>
- on systems where the IP address is not predictable - for
- example if you have a dynamic IP address with your ISP, and
- you are using some variety of dynamic DNS solution. Since
- <code>*</code> matches any IP address, this configuration
- would work without changes whenever your IP address
- changes.</p>
- </div>
-
- <p>The above configuration is what you will want to use in almost
- all name-based virtual hosting situations. The only thing that this
- configuration will not work for, in fact, is when you are serving
- different content based on differing IP addresses or ports.</p>

-
- <p>The server machine has two IP addresses (<code>192.168.1.1</code>
- and <code>172.20.30.40</code>). The machine is sitting between an
- internal (intranet) network and an external (internet) network. Outside
- of the network, the name <code>server.example.com</code> resolves to
- the external address (<code>172.20.30.40</code>), but inside the
- network, that same name resolves to the internal address
- (<code>192.168.1.1</code>).</p>
-
- <p>The server can be made to respond to internal and external requests
- with the same content, with just one <code>VirtualHost</code>
- section.</p>
-
- <div class="example"><h3>Server configuration</h3><p><code>

- <p>Now requests from both networks will be served from the same

-
- <div class="note">
- <h3>Note:</h3><p>On the internal

- than the fully qualified host name
- <code>server.example.com</code>.</p>
-
- <p>Note also that, in the above example, you can replace the list
- of IP addresses with <code>*</code>, which will cause the server to

- at <code>192.168.111.2</code>. The <code class="directive"><a href="../mod/mod_proxy.html#proxypreservehost on">ProxyPreserveHost On</a></code> directive is

- <p>Using such a default vhost with a wildcard port effectively prevents

-
- <p>A default vhost never serves a request that was sent to an
- address/port that is used for name-based vhosts. If the request
- contained an unknown or no <code>Host:</code> header it is always

-
- <p>The default vhost for port 80 (which <em>must</em> appear before any

-
- <p>The name-based vhost with the hostname
- <code>www.example2.org</code> (from our <a href="#name">name-based</a> example, setup 2) should get its own IP
- address. To avoid problems with name servers or proxies who cached the
- old IP address for the name-based vhost we want to provide both
- variants during a migration phase.<br />
- The solution is easy, because we can simply add the new IP address
- (<code>172.20.30.50</code>) to the <code>VirtualHost</code>
- directive.</p>

- <div class="example"><h3>Server configuration</h3><p><code>

-
- Listen 80<br />
- ServerName www.example1.com<br />
- DocumentRoot /www/example1<br />
- <br />
- NameVirtualHost 172.20.30.40<br />
- <br />
- &lt;VirtualHost 172.20.30.40 172.20.30.50&gt;<br />
- <span class="indent">
- DocumentRoot /www/example2<br />

- <p>The vhost can now be accessed through the new address (as an
- IP-based vhost) and through the old address (as a name-based
- vhost).</p>

-<h2><a name="serverpath" id="serverpath">Using the <code>ServerPath</code>
- directive</a></h2>
-
- <p>We have a server with two name-based vhosts. In order to match the
- correct virtual host a client must send the correct <code>Host:</code>
- header. Old HTTP/1.0 clients do not send such a header and Apache has
- no clue what vhost the client tried to reach (and serves the request
- from the primary vhost). To provide as much backward compatibility as
- possible we create a primary vhost which returns a single page
- containing links with an URL prefix to the name-based virtual
- hosts.</p>
-
- <div class="example"><h3>Server configuration</h3><p><code>
-
-
- NameVirtualHost 172.20.30.40<br />
- <br />
- &lt;VirtualHost 172.20.30.40&gt;<br />
- <span class="indent">
- # primary vhost<br />
- DocumentRoot /www/subdomain<br />
- RewriteEngine On<br />
- RewriteRule ^/.* /www/subdomain/index.html<br />
- # ...<br />
- </span>
- &lt;/VirtualHost&gt;<br />
- <br />
- &lt;VirtualHost 172.20.30.40&gt;<br />

- <span class="indent">
- ServerName www.sub1.domain.tld<br />
- ServerPath /sub1/<br />
- RewriteEngine On<br />
- RewriteRule ^(/sub1/.*) /www/subdomain$1<br />
- # ...<br />
- </span>
- &lt;/VirtualHost&gt;<br />
- <br />
- &lt;VirtualHost 172.20.30.40&gt;<br />

-
- <p>Due to the <code class="directive"><a href="../mod/core.html#serverpath">ServerPath</a></code>
- directive a request to the URL
- <code>http://www.sub1.domain.tld/sub1/</code> is <em>always</em> served
- from the sub1-vhost.<br /> A request to the URL
- <code>http://www.sub1.domain.tld/</code> is only
- served from the sub1-vhost if the client sent a correct
- <code>Host:</code> header. If no <code>Host:</code> header is sent the
- client gets the information page from the primary host.<br />
- Please note that there is one oddity: A request to
- <code>http://www.sub2.domain.tld/sub1/</code> is also served from the
- sub1-vhost if the client sent no <code>Host:</code> header.<br />
- The <code class="directive"><a href="../mod/mod_rewrite.html#rewriterule">RewriteRule</a></code> directives
- are used to make sure that a client which sent a correct
- <code>Host:</code> header can use both URL variants, <em>i.e.</em>,
- with or without URL prefix.</p>
