    <p>Der Begriff <cite>virtueller Host</cite> <span class="transnote">(<em>Anm.d.�.:</em> engl. 'virtual
    host')</span> bezieht sich auf die Praxis, mehr als ein Webangebot
    (z.B. <code>www.company1.com</code> und <code>www.company2.com</code>)
    auf einer einzigen Maschine zu betreiben. Virtuelle Hosts k�nnen
    "<a href="ip-based.html">IP-basiert</a>" sein, was bedeutet, dass jedes
    Webangebot eine andere IP besitzt, oder  "<a href="name-based.html">Namens-basiert</a>", was bedeutet, dass
    unter jeder IP-Adresse mehrere Namen laufen. Die Tatsache, dass sie
    auf dem gleichen physischen Server laufen, ist f�r den Endbenutzer
    nicht offensichtlich.</p>

    <p>Der Apache war einer der ersten Server, der IP-basierte
    virtuelle Hosts von Haus aus direkt unterst�tzt hat. Seit Version 1.1
    unterst�tzt der Apache sowohl IP-basierte als auch namensbasierte
    virtuelle Hosts (vhosts). Letzteres wird zuweilen auch
    <em>Host-basiert</em> oder <em>non-IP-Virtual-Host</em> genannt.</p>

    <p>Nachfolgend finden Sie eine Liste von Dokumenten, die alle Details
    der Unterst�tzung von virtuellen Hosts ab Apache Version 1.3
    beschreiben.</p>

    <p>Bei der Suche von Fehlern in Ihrer Virtual-Host-Konfiguration ist
    die Apache-Befehlszeilenoption <code>-S</code> m�glicherweise
    hilfreich. Geben Sie dazu den folgenden Befehl ein:</p>

    <div class="example"><p><code>
    /usr/local/apache2/bin/httpd -S
    </code></p></div>

    <p>Diese Anweisung gibt eine Beschreibung aus, wie der Apache die
    Konfigurationsdatei analysiert hat. Eine sorgf�ltige
    �berpr�fung der IP-Adressen und Servernamen kann helfen,
    Konfigurationsfehler aufzudecken. (Lesen Sie die Dokumentation zum
    <code class="program"><a href="../programs/httpd.html">httpd</a></code>-Programm f�r weitere
    Befehlszeilenoptionen.)</p>
