One of my server has $_SERVER['HTTP_CONNECTION'] is set to close need to set it to keep-alive in my phpinfo() any idea where to change that?

Apache config has 

KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 100

Am I doing something wrong?

$_SERVER['HTTP_CONNECTION'] is the value of the HTTP Connection header sent as part of the request by the client. It is not a server setting. You cannot change it and you cannot force the client to send another value in that header. It's up to the client.

    On another server of mine its set to $_SERVER['HTTP_CONNECTION'] = "keep-alive" in my phpinfo – BlackBird Jun 28 '12 at 10:45
  • What does that mean? It's still a value sent by the client. You're probably just seeing the same value as output by `$_SERVER`. – deceze Jun 28 '12 at 10:50

    When i do phpinfo() on two different servers. Apache Environmental variable HTTP_CONNECTION for one of the server is close and one of the server is keep-alive. How does that vary? – BlackBird Jun 28 '12 at 10:51
  • Not sure. Inspect your traffic in detail, who is sending what header. See http://en.wikipedia.org/wiki/HTTP_persistent_connection – deceze Jun 28 '12 at 10:54

Contents of the Connection: header from the current request, if there is one.
