+ * @short_description: Soup session state object
+ *
+ * #SoupSession is the object that controls client-side HTTP. A
+ * #SoupSession encapsulates all of the state that libsoup is keeping
+ * on behalf of your program; cached HTTP connections, authentication
+ * information, etc.
+ *
+ * Most applications will only need a single #SoupSession; the primary
+ * reason you might need multiple sessions is if you need to have
+ * multiple independent authentication contexts. (Eg, you are
+ * connecting to a server and authenticating as two different users at
+ * different times; the easiest way to ensure that each #SoupMessage
+ * is sent with the authentication information you intended is to use
+ * one session for the first user, and a second session for the other
+ * user.)
+ *
+ * #SoupSession itself is an abstract class, with two subclasses. If
+ * you are using the glib main loop, you will generally want to use
+ * #SoupSessionAsync, which uses non-blocking I/O and callbacks. On
+ * the other hand, if your application is threaded and you want to do
+ * synchronous I/O in a separate thread from the UI, use
+ * #SoupSessionSync.
