ACE30 load balancing across two slightly different rservers

[rjuchta]

Hi,

is there a possibility to get a load balancing across two rservers so:

when client sends http://vip/ and it goes to rserver1 then url is sent without change

when client sends http://vip/ and it goes to rserver2 then url is modified to http://vip/xyz/

Or maybe load balancing can be done across two serverfarms ?

thanks

Ryszard,

I hope you are doing great.

I do not think that´s possible since the ACE just load balance the traffic to the servers and once the load balance decision has been taken it will pass the "ball" to the chosen server.

Think about this, let´s say user A needs to go to Server1 but guess what? based on the load balance decision it was sent to Server2 which unfortunately does not have what the customer was looking for. OK, fine, user A close the connection and tries again but now the Server1 is down then the only available is Server2 then the ACE sends it to Server2 again then user A just decides to leave, you see how bad that can be.

A better approach would be to have either 2 VIPs ( different IP addresses) or 2 with the same IP address but hearing on another port, perhaps, one port per server.

Hope this helps!

Hi Jorge,

thanks for the suggestion. I'm going to take the approach with 2 VIPs.
