That is actually intended exactly as written The XMPP method will work better behind firewalls, since the HTTP method requires a direct (unsolicited) connection from the event generator. XMPP allows the client to maintain an outbound connection to the XMPP server which can be used to return notifications.

XMPP is a client-initiated protocol though - no holes need to be punched in the firewall. The protocol definition also includes mechanisms for HTTP tunnelling, so you can work behind HTTP/HTTPS-only proxies. Getting unsolicited web requests in would be substantially harder than getting an XMPP connection out.
