We have a situation here at work where we are about to significantly increase the number of users going through our load balancers (csm-s version 2.1(4) ).
The application guys have asked whether there is a way to limit the number of connections allowed and if that limit is exceeded then send users to a different server with a "application busy" type error page. Not ideal but it will be a while before they can upgrade their infrastructure. i have a few quick questions.
1) If i have a maxconns limit under the vserver config and that limit is reached does it then use a defined backup serverfarm.
2) if the maxconns is reached and the CSM-S uses the backup serverfarm, are the real servers marked as out-of-service. If so presumably they are put back in service once the number of connections falls below the maxconns limit.
3)If the reals are marked out-of-service will existing user connections be serviced (they will be using sticky).
4) Is there a better way to do this with the CSM-S
