 From the Apache documentation 

    The Keep-Alive extension to HTTP/1.0 and the persistent connection
    feature of HTTP/1.1 provide long-lived HTTP sessions which allow
    multiple requests to be sent over the same TCP connection. In some
    cases this has been shown to result in an almost 50% speedup in
    latency times for HTML documents with many images. To enable
    Keep-Alive connections, set |KeepAlive On|.

    For HTTP/1.0 clients, Keep-Alive connections will only be used if
    they are specifically requested by a client. In addition, a
    Keep-Alive connection with an HTTP/1.0 client can only be used when
    the length of the content is known in advance. This implies that
    dynamic content such as CGI output, SSI pages, and server-generated
    directory listings will generally not use Keep-Alive connections to
    HTTP/1.0 clients. For HTTP/1.1 clients, persistent connections are
    the default unless otherwise specified. If the client requests it,
    chunked encoding will be used in order to send content of unknown
    length over persistent connections.
