0001158: HttpProxyServlet enhancements
(rep by S Nagar)

1) The HttpProxyServlet is a straight round robin load balancer. Compare to LoadBalanceServlet which uses a least cost algorithm to choose the backend with the least amount of load

2) The HttpProxyServlet will keep trying a backend server that is down. Compare to LoadBalanceServlet which uses a timeout value, if a backend server goes down it only tries it once every 5 seconds to see if it is back up again.

3) The HttpProxyServlet will not use sticky sessions. If balancing to two backend IIS servers the sessions will not be sticky.

Please can you update on this bug. Also I would like to add that when using the proxy servlet to proxy request to an IIS server its time outs and it seems this issues was raised earlier as well and fixed in 3.0.19 but seems to have reappeared again.

Running:
