Header Keep-Alive

I'm trying to increase the connection timeout; but can't get it to work. Note: Keep-Alive gets repeated. I'm using: header("Connection: Keep-Alive"); header("Keep-Alive: timeout=9, max=100"); I get: (Status-Line) HTTP/1.1 200 OK Date Mon, 27 May 2013 20:19:54 GMT Server Apache Connection Keep-Alive, Keep-Alive Keep-Alive timeout=5, max=100 Expires Thu, 19 Nov 1981 08:52:00 GMT Cache-Control no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma no-cache Content-Encoding gzip Vary Accept-Encoding,User-Agent Set-Cookie Coach::VermontCamp2013_setupMode=58d7e534bec4ec57634c78caa59d8db2; expires=Sat, 23-Nov-2013 20:19:55 GMT; path=/Coach/; domain=.ridersite.org Transfer-Encoding chunked Content-Type text/html; charset=utf-8
