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