Using LTM to SSL Offload a APM Server

Just curious here, but can you elaborate on the reasoning to use two virtual servers? APM is a module that runs on top of LTM and is ultimately dependent on an LTM virtual server. Offloading SSL at the LTM VIP that has an access policy applied should not be any slower than an SSL offloading LTM VIP that then load balances to an APM VIP. Can you perhaps also elaborate on your APM configuration?

To pass traffic from one VIP to another on the same box, you would use the virtual command in an iRule on the external VIP, using the name of the internal VIP as reference:

when CLIENT_ACCEPTED {
    virtual [name of internal VIP]
}
