+ * Ein ganz einfacher Web-Server auf TCP und einem

+ * Seitenanforderungen lokal zu dem Verzeichnis, 
+ * aus dem er gestartet wurde, zu bearbeiten. Wurde 
+ * der Server z.B. im Verzeichnis c:\tmp gestartet, so
+ * würde eine Seitenanforderung 
+ * http://localhost:80/test/index.html die Datei 
+ * c:\tmp\test\index.html laden. CGIs, SSIs, Servlets 
+ * oder ähnliches wird nicht unterstützt.
+ * <p>
+ * Die Dateitypen .htm, .html, .gif, .jpg und .jpeg werden
+ * erkannt und mit korrekten MIME-Headern übertragen, alle
+ * anderen Dateien werden als "application/octet-stream" 
+ * übertragen. Jeder Request wird durch einen eigenen 
+ * Client-Thread bearbeitet, nach Übertragung der Antwort
+ * schließt der Server den Socket. Antworten werden mit 
+ * HTTP/1.0-Header gesendet.
