Ace Ip Address Stickiness and conn-limit

[sergegaron]

In my case, Ace are configured with Ip source address stickiness. Eight servers in each server farms. Everything works well. However, I would like to know how the ace would react if, in a server farm, I configure a conn-limit on the real servers. If rserver1 reach the limit, and a new user on a citrix server (already sticky to the rserver1) try to establish a new connection, what will happen? I think that he won't be able to connect because the citrix server from where he is working is already sticky to rserver1. Is that the case?

Thanks in advance,

the server is considered down and a new one selected.

So the connection will go through to a different server and the sticky table will be adjusted so next connections will also go to the new server.

You said that the server which has reached the conn-limit will be considered down so: will the existing connections on that server be broken?

thanks,

Down, means not usable for NEW connection.

But active connections are not affected.

The problem will be for SESSION already connected but requesting a new connection....those connections will not be able to get to the same server since it is down (at maxconn limit) and therefore the new connection will be sent to a different server with the sticky entry rewritten.

If the session fails due to this, a new one will be restarted and all new connections will follow the sticky entry to the new rserver.
