<p>
<a class="link" href="SoupLogger.html" title="SoupLogger"><span class="type">SoupLogger</span></a> watches a <a class="link" href="SoupSession.html" title="SoupSession"><span class="type">SoupSession</span></a> and logs the HTTP traffic that
it generates, for debugging purposes. Many applications use an
environment variable to determine whether or not to use
<a class="link" href="SoupLogger.html" title="SoupLogger"><span class="type">SoupLogger</span></a>, and to determine the amount of debugging output.
</p>
<p>
To use <a class="link" href="SoupLogger.html" title="SoupLogger"><span class="type">SoupLogger</span></a>, first create a logger with <a class="link" href="SoupLogger.html#soup-logger-new" title="soup_logger_new ()"><code class="function">soup_logger_new()</code></a>,
optionally configure it with <a class="link" href="SoupLogger.html#soup-logger-set-request-filter" title="soup_logger_set_request_filter ()"><code class="function">soup_logger_set_request_filter()</code></a>,
<a class="link" href="SoupLogger.html#soup-logger-set-response-filter" title="soup_logger_set_response_filter ()"><code class="function">soup_logger_set_response_filter()</code></a>, and <a class="link" href="SoupLogger.html#soup-logger-set-printer" title="soup_logger_set_printer ()"><code class="function">soup_logger_set_printer()</code></a>,
and then attach it to a session (or multiple sessions) with
<a class="link" href="SoupSession.html#soup-session-add-feature" title="soup_session_add_feature ()"><code class="function">soup_session_add_feature()</code></a>.
</p>
<p>
By default, the debugging output is sent to
<code class="literal">stdout</code>, and looks something like:
</p>
<p>
</p>
<div class="informalexample"><pre class="screen">
> POST /unauth HTTP/1.1
> Soup-Debug-Timestamp: 1200171744
> Soup-Debug: SoupSessionAsync 1 (0x612190), SoupMessage 1 (0x617000), SoupSocket 1 (0x612220)

</pre></div>
<p>
</p>
<p>
The <code class="literal">Soup-Debug-Timestamp</code> line gives the time (as
a <span class="type">time_t</span>) when the request was sent, or the response fully
received.
</p>
<p>
The <code class="literal">Soup-Debug</code> line gives further debugging
information about the <a class="link" href="SoupSession.html" title="SoupSession"><span class="type">SoupSession</span></a>, <a class="link" href="SoupMessage.html" title="SoupMessage"><span class="type">SoupMessage</span></a>, and <a class="link" href="SoupSocket.html" title="SoupSocket"><span class="type">SoupSocket</span></a>
involved; the hex numbers are the addresses of the objects in
question (which may be useful if you are running in a debugger).
The decimal IDs are simply counters that uniquely identify objects
across the lifetime of the <a class="link" href="SoupLogger.html" title="SoupLogger"><span class="type">SoupLogger</span></a>. In particular, this can be
used to identify when multiple messages are sent across the same
connection.
</p>
<p>
Currently, the request half of the message is logged just before
the first byte of the request gets written to the network (from the
<a class="link" href="SoupSession.html#SoupSession-request-started" title='The "request-started" signal'><span class="type">"request_started"</span></a> signal), which means that if you have
not made the complete request body available at that point, it will
not be logged.
</p>
<p>
The response is logged just after the last byte of the response
body is read from the network (from the <a class="link" href="SoupMessage.html#SoupMessage-got-body" title='The "got-body" signal'><span class="type">"got_body"</span></a> or
<a class="link" href="SoupMessage.html#SoupMessage-got-informational" title='The "got-informational" signal'><span class="type">"got_informational"</span></a> signal), which means that the
<a class="link" href="SoupMessage.html#SoupMessage-got-headers" title='The "got-headers" signal'><span class="type">"got_headers"</span></a> signal, and anything triggered off it
(such as <a class="link" href="SoupSession.html#SoupSession-authenticate" title='The "authenticate" signal'><span class="type">"authenticate"</span></a>) will be emitted
<span class="emphasis"><em>before</em></span> the response headers are actually
logged.
</p>
<p>
If the response doesn't happen to trigger the
<a class="link" href="SoupMessage.html#SoupMessage-got-body" title='The "got-body" signal'><span class="type">"got_body"</span></a> nor <a class="link" href="SoupMessage.html#SoupMessage-got-informational" title='The "got-informational" signal'><span class="type">"got_informational"</span></a> signals
due to, for example, a cancellation before receiving the last byte
of the response body, the response will still be logged on the
event of the <a class="link" href="SoupMessage.html#SoupMessage-finished" title='The "finished" signal'><span class="type">"finished"</span></a> signal.
