|
||
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>By default neon will use a persistent connection
|
||
whenever possible. For specific applications, or for debugging
|
||
purposes, it is sometimes useful to disable persistent connections.
|
||
The <code class="function">ne_set_persist</code> function will disable
|
||
persistent connections if passed a <code class="parameter">flag</code>
|
||
parameter of <code class="literal">0</code>, and will enable them
|
||
otherwise.</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>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" lang="en"><a name="id2938531"></a><h2>Examples</h2><p>Set a user-agent string:</p><pre class="programlisting">ne_session *sess = ne_session_create(...);
