+==== HTTP/2 Support
+
+CometD applications are typically independent of the transport used to send or
+receive messages.
+
+However, if the transport is HTTP/2, CometD can be configured to take advantage
+of the HTTP/2 transport by removing the limit on the number of outstanding long
+polls, see the `http2MaxSessionsPerBrowser` parameter below.
+
+Where before a CometD applications opened in multiple browser tabs only had one
+tab performing the long poll (and all the other tabs performing a normal poll),
+now with HTTP/2 it is possible to remove this limitation and have all the tabs
+performing the long poll.
