44 If the idle interval is set, this setting affects the behavior of the stream
45 when no data is received for the timeout interval as follows:
47 <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
49 When <code class="computeroutput"><span class="identifier">keep_alive_pings</span></code>
50 is <code class="computeroutput"><span class="keyword">true</span></code>, an idle ping
51 will be sent automatically. If another timeout interval elapses with
52 no received data then the connection will be closed. An outstanding
53 read operation must be pending, which will complete immediately the
54 error <a class="link" href="../boost__beast__error.html" title="error"><code class="computeroutput"><span class="identifier">timeout</span></code></a>.
57 When <code class="computeroutput"><span class="identifier">keep_alive_pings</span></code>
58 is <code class="computeroutput"><span class="keyword">false</span></code>, the connection
59 will be closed. An outstanding read operation must be pending, which
