to identify the software which generated the request for statistical
or debugging purposes.  neon does not send a
<code class="literal">User-Agent</code> header unless a call is made to the
<code class="function">ne_set_useragent</code>.
<code class="function">ne_set_useragent</code> must be passed a product string
conforming to RFC2616's product token grammar; of the form
<code class="literal">"Product/Version"</code>.</p><p>When neon reads from a socket, by default the read
operation will time out after 60 seconds, and the request will fail
giving an <span class="errorcode">NE_TIMEOUT</span> error.  To configure this
timeout interval, call <code class="function">ne_set_read_timeout</code> giving
the desired number of seconds as the <code class="parameter">timeout</code>
parameter.</p><p>When a connection is being established to a server,
	normally only the system's TCP timeout handling will apply.
	To configure a specific (and probably shorter) timeout, the
	<code class="function">ne_set_connect_timeout</code> can be used,
	giving the desired number of seconds as the
	<code class="parameter">timeout</code> parameter.  If
	<code class="literal">0</code> is passed, then the default behaviour of
	using the system TCP timeout will be used.</p><p>The scheme used to initially create the session will be
         returned by <code class="function">ne_get_scheme</code>.</p><p>The hostport pair with which the session is associated
         will be returned by the
         <code class="function">ne_get_server_hostport</code>; for example
         <code class="literal">www.example.com:8080</code>.  Note that the
         <code class="literal">:port</code> will be omitted if the default port
         for the scheme is used.</p></div><div class="refsect1"><a name="idm140368849963552"></a><h2>Examples</h2><p>Set a user-agent string:</p><pre class="programlisting">ne_session *sess = ne_session_create(...);
