    [ https://issues.apache.org/jira/browse/GUACAMOLE-1022?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17104561#comment-17104561 ] 

Jerome Charaoui commented on GUACAMOLE-1022:
--------------------------------------------

I've been testing session affinity and I also think there could be improvements.

For example, if a connection becomes unavailable because the connexion weight is changed to "-1", the Load Balanced Group will fail for that user until they log out. The same happens if the client was disconnected, and in the mean time another user logged into the target computer.

In both of these cases the error message displayed is "This connection is currently in use, and concurrent access to this connection is not allowed. Please try again later." If the user doesn't care about their previous connection, it's not clear at all that what they need to do is log out and log back in.

Perhaps a more acceptable approach to this problem would be to implement *optional* failover. If for whatever reason the client is unable to reestablish the connection using the affinity parameter, instead of failing hard it could display a more informative error message which includes the option to attempt to reconnect to the Load Balanced Group while ignoring affinity parameters. For example:

"We were unable to reconnect you to your previous connection. Would you like to attempt to reconnect using a new connection?"

> I have 78 hosts in a balanced connection group.  Let's say that the first host is down.  Now, when the user click on the connection group expecting to get a connection, they instead get a message that Guacamole can't connect.  If it can't connect to the first one, it should try the next one, then the next one until it finds one that works.
