MIME-Typen
Mime(Multipurpose Internet Mail Extensions)-Typen dienen zur Angabe von Dateitypen. Das ist notwendig, da längst nicht alle Betriebssysteme mit Dateiendungen arbeiten. Selbst bei Windows sind die Endungen nicht immer eindeutig. Die korrekte Angabe des mime-types, etwa bei der Übetragung von Formulardaten oder dem Einsatz von Multimedia-Objekten, sorgt für eine einwandfreie Übertragung und Darstellung. Andernfalls werden z.B. Sonderzeichen codiert oder Inhalte gar nicht wiedergegeben.
Ein Beispiel für die Verwendung gibt es hier auch.
