Summary	0003984: SymmetricDS doesn't respect the sticky session setting for AWS ELB ALB which can result in resending logging when under stress
Description	For the push protocol, SymmetricDS does an HTTP HEAD to reserve a connection and then an HTTP PUT to push the data. The reservation of the connection requires that the subsequence PUT happen on the same server. This requires the load balancer to have sticky sessions configured. The AWS ELB ALB implementation of a load balancer uses cookies to track the session. SymmetricDS isn't currently configured to send cookies received for a domain on subsequent requests. This can be done in Java by calling the following code (it only needs to be done once for the JVM). if (java.net.CookieHandler.getDefault() == null) { java.net.CookieHandler.setDefault(new java.net.CookieManager()); }

chenson 2019-05-30 17:27 administrator ~0001513	The logging on both the server and the client side could probably be improved to detect the failure scenario to give the user a clue as to what is going wrong.
