Need assistence with limiting connections

I've set the node's connection limit to 1 for testing... I have this iRule in place:

 

 

when LB_FAILED {

 

LB::reselect pool pool "name"

 

}

 

 

Question:

 

 

When the 2nd user logs on, I want the 1st person to maintain their session and NOT have him get disconnected. Any suggestions on what I can add to this iRule so the 2nd will be re-directed to a different site??? If a better iRule exist, please share.
