+ * as a content-type by default. This is a problem for some clients, because
+ * they expect a correct contenttype.
+ *
+ * There's really no accurate, fast and portable way to determine the contenttype
+ * so this extension does what the rest of the world does, and guesses it based
+ * on the file extension.
