I am using RF 4.2.3 FINAL and a4j:push.
All works well, but I am wondering why RF (or the underlying Athmosphere) does not use X-Atmosphere-Transport: SSE.
I am using JBOSS 7.1.1 FINAL and Servlet 3.0.
So ServerSentEvents (SSE) should be possible.
Can I change it to SSE? And if so, how can I adjust it in Richfaces?
