SSL Related Irule

I am trying to connect to our application using PKI and I have installed the cert onto the bigip adn assigned it to the Virtual Server. I am trying to find a rule that will look for a client cert and if they do not have one they will be sent to a different pool than the clients that have a cert. Also, does anyone know if you need to have the server side SSL profile assigned to the virtual server in order for this to work properly? Or any other information about using PKI with the bigip...
