Websense Content Gateway Assistant iApp

Hi, we have a scenario where we require iRule functionality while using this iApp. We need to decrypt the traffic before it is sent to Websense so that iRules can process the request. If we create the clientssl profile with a certificate and key then we can successfully achieve this, however the browsers rightfully complain because there is a certificate name mismatch for the target web server, do you know how we can accomplish this?
