+ and you want to respond differently for <code>www.example.com</code>
+ and <code>www.example.org</code>.</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
+ <code>hosts</code> entries.</p>
+ </div>

+ ServerName www.example.org
+
+ # Other directives here
+&lt;/VirtualHost&gt;</pre>
+
+
+ <p>The asterisks match all addresses, so the main server serves no
+ requests. Due to the fact that the virtual host with
+ <code>ServerName www.example.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 class="directive"><a href="../mod/core.html#servername">ServerName</a></code> directives, it will be served by this first
+ <code class="directive"><a href="../mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code>.</p>
+
+ <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>
+
+ <div class="note">
+ <h3>Note</h3>
+
+ <p>You may replace <code>*</code> with a specific IP address
+ on the system. Such virtual hosts will only be used for
+ HTTP requests received on connection to the specified IP
+ address.</p>
+
+ <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>

+ <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.</p>
+
+ <p>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.</p>
+
+ <p>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>
