We are using a pair of 11501s to load balance HTTPS traffic to a pair of web servers.
We configure the least connection as the balancing method. But, somehow, web server 1 receive double connections than web server 2.
We suppose the connection to both web servers should be the same.
Because of stickyness !!!
If one server went down or if you started with one server first and then added the other one, the sticky function will force the clients to stick to the same server (the first one) even if this server is overloaded.
This is the purpose of stickyness.
clear the sticky table now that all servers are up and you should get an equal load.
W/ stickyness we can't guarantee that the load will be equal on all the servers.
For example, if you have just 2 machine accessing your VIP.
One machine is sent to Server1 and the other one to server2.
If the first machine opens 10 connections and the 2nd one only 1, you get 10 connections to server 1 and 1 connection to server2.
Totally unequal loadbalancing.
Without stickyness, you would see 5/6 or 6/5.
