Hi Jody!

I see what you mean, and you have a point, and I did not know the answer. So I did an experiment. Set the maximum connections in firefox to 1 and then added the following rule on my VIP:

when CLIENT_ACCEPTED {
    log local0. "New connection. Client port [TCP::client_port]"
}

when LB_SELECTED {
    log local0. "LB Selected. Client port [TCP::client_port]"
}

This is the log

Mar 14 09:09:16 LB1 info tmm2[12112]: Rule /Partition/iruletest : New connection. Client port 18482
Mar 14 09:09:17 LB1 info tmm2[12112]: Rule /Partition/iruletest : LB Selected. Client port 18482
Mar 14 09:09:17 LB1 info tmm2[12112]: Rule /Partition/iruletest : LB Selected. Client port 18482

Looks like it's triggered everytime.

IF it does not work, we could try to reselect the member via the pool command in the HTTP_REQUEST event, but it will be messier. 🙂
