public sealed class ContentSniffer : Object, SessionFeature
Sniffs the mime type of messages.
A [class@ContentSniffer] tries to detect the actual content type of the files that are being downloaded by looking at some of the data
before the [class@Message] emits its [signal@Message:SoupContentSniffer:got-headerss] signal. [class@ContentSniffer]
implements [iface@SessionFeature], so you can add content sniffing to a session with [method@Session.add_feature] or [
method@Session.add_feature_by_type].
