We are in the process of doing a POC on AJAX push technology. Some of the things we are looking at are Ice Faces Push Technology, Richfaces a4j:push and WebSphere Application Server Feature Pack for Web 2.0.
We find an issue with WebSphere Application Server Feature Pack for Web 2.0 in that going down this road we become a slave to the number of connections that the browser will allow.
So wondering if anyone has used this solution and if they were able to get around this connection issue and what they did to accomplish it.
