+--------------------------
+Don't cache @@xmpp-loader:
+--------------------------
+
+Make sure the **${site_url}/@@xmpp-loader** URL isn't cached. This view
+returns an authentication token which has to be different each time you
+reload your page.
+
+If you cache this, the token won't change and you won't be able to communicate
+with the XMPP server.
