[Need help] HTTP Response Headers - Keep-Alive

[kohkindachi]

Hey guys, one of my server phpinfo is showing

HTTP Response Headers
X-Powered-By PHP/5.1.6
Keep-Alive timeout=1, max=128
Connection Keep-Alive
Transfer-Encoding chunked Content-Type text/html; charset=UTF-8

While the other is showing:

HTTP Response
Headers X-Powered-By PHP/5.1.6
Connection close
Transfer-Encoding chunked
Content-Type text/html; charset=UTF-8

How do i change the connection and keep-alive portion? What does 'close' means?
