<p>By default, HTTP sessions use HTTP/1.1. To use HTTP/1.0, the connection
information property <codeph>HTTP::EHTTPVersion</codeph> must be set to <codeph>HTTP::EHttp10</codeph>. </p>

<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>
