ACString nsIContentSniffer::getMIMETypeFromContent	(	in nsIRequest	aRequest,
		[const, array, size_is(aLength)] in octet	aData,
		in unsigned long	aLength
	)

Given a chunk of data, determines a MIME type.

Information from the given request may be used in order to make a better decision.

Parameters:

	aRequest	The request where this data came from. May be null.
	aData	Data to check
	aLength	Length of the data

Exceptions:

NS_ERROR_NOT_AVAILABLE

if no MIME type could be determined.

Note:: Implementations should consider the request read-only. Especially, they should not attempt to set the content type property that subclasses of nsIRequest might offer.
