14 <p>By default, HTTP sessions use HTTP/1.1. To use HTTP/1.0, the connection |

33 <p>The version chosen will apply to all new transactions following the property |
|
34 change, but will not affect any transactions currently in progress.</p> |
|
35 <p>As HTTP/1.1 mandates the use of a persistent connection for requests made |
|
36 in series to a single origin server, the default behaviour of HTTP Client |
|
37 is to set up persistent connections for each transaction. This can be overridden |
|
38 by specifying a Connection header in the client request. </p> |
