* [[HTTP Persistent Connections]]

=Overview=

It is the client that initially requests the connection to be kept alive. The persistent connection is initiated by specifying a "Keep-Alive" value for the "Connection" request header:

<pre>
GET ... HTTP/1.0
Host: ...
Connection: Keep-Alive
</pre>

The server may or may not support persistent connections. If the server does support them, it will confirm that by including with the response a "Connection" response header:

<pre>
200 OK
Content-Length: ...
Connection: Keep-Alive
</pre>

Once both the client and the server have agreed on using persistent connections, they will keep the underlying TCP/IP connection open, and subsequent requests from that client will be sent over the persistent connection.
