Hi Amit, If you want to do round-robin and stickyness, the best way is to use coukies, either inserting one or learning an application cookie. Some explanations and examples provided here: http://blog.exceliance.fr/2012/03/29/load-balancing-affinity-persistence-sticky-sessions-what-you-need-to-know/ Concerning the timeout you want to achieve, you're misunderstanding client and server timeouts. You may want also to enable "retry" and "option redispatch" to tell haproxy to forward the request to an other server if the one it was trying to get connected is failaing at the moment of the request. That way, the timeout connect will be used and if HAProxy can't be connected. Regards
