Some of them do when talking to HTTP/1.0 clients, where persistent
connections aren't default.  For example:

$ wget http://www.apache.org
--16:01:44--  http://www.apache.org/
[...]
 8 Keep-Alive: timeout=5, max=100
 9 Connection: Keep-Alive

To be on the safe side, Wget supports both response headers.
