<p>
<a class="link" href="SoupSessionFeature.html" title="SoupSessionFeature"><span class="type">SoupSessionFeature</span></a> is the interface used by classes that extend
the functionality of a <a class="link" href="SoupSession.html" title="SoupSession"><span class="type">SoupSession</span></a>. Some features like HTTP
authentication handling are implemented internally via
<a class="link" href="SoupSessionFeature.html" title="SoupSessionFeature"><span class="type">SoupSessionFeature</span></a>s. Other features can be added to the session
by the application. (Eg, <a class="link" href="SoupLogger.html" title="SoupLogger"><span class="type">SoupLogger</span></a>, <a class="link" href="SoupCookieJar.html" title="SoupCookieJar"><span class="type">SoupCookieJar</span></a>.)
</p>
<p>
See <a class="link" href="SoupSession.html#soup-session-add-feature" title="soup_session_add_feature ()"><code class="function">soup_session_add_feature()</code></a>, etc, to add a feature to a session.
