device for data sent by the web browser</p> <p>QxtWebContent is a read-only <a href="http://doc.qtsoftware.com/4.5/qiodevice.html">QIODevice</a> subclass that encapsulates data sent from the web browser, for instance in a POST or PUT request.</p> <p>In order to avoid delays while reading content sent from the client, and to insulate multiple pipelined requests on the same connection from each other, <a href="qxtweb.html">QxtWeb</a> uses QxtWebContent as an abstraction for streaming data.</p> <p>See also <a href="qxtabstractwebservice.html">QxtAbstractWebService</a>.</p> <hr /> <h2>Member
