Dear All,


I try to load balance websockets-based services of grizzly servers running on port 7777, but failed to do it with HAProxy 1.4.20.

Following the page by Jean-Francois: http://jfarcand.wordpress.com/2011/10/06/configuring-haproxy-for-websocket/, it is not working.

Connection refused for my wss -based connections. Work when reaching the servers directly but not when through the HAProxy. Connection refused, :(

Had anybody luck with HAProxy and Grizzly web socket?



Thank you in advance!

Regards,

Imre
