A SoupContentSniffer tries to detect the actual content type of
the files that are being downloaded by looking at some of the data
before the SoupMessage emits its “got-headers” signal.
SoupContentSniffer implements SoupSessionFeature, so you can add
content sniffing to a session with soup_session_add_feature() or
soup_session_add_feature_by_type().
SoupContentSniffer *
soup_content_sniffer_new (void);
Creates a new SoupContentSniffer.
Since 2.28
char * soup_content_sniffer_sniff (SoupContentSniffer *sniffer,SoupMessage *msg,SoupBuffer *buffer,GHashTable **params);
Sniffs buffer
 to determine its Content-Type. The result may also
be influenced by the Content-Type declared in msg
's response
headers.

 the sniffed Content-Type of buffer

but may be "application/octet-stream".
Since 2.28
gsize
soup_content_sniffer_get_buffer_size (SoupContentSniffer *sniffer);
Gets the number of bytes sniffer
 needs in order to properly sniff
a buffer.
