APM Session Variable Not Being Cached

I updated my Client Inspection rule to be: * expr { [mcget {session.ssl.cert.subject}] == "subject.domainname.com" } I also updated my Logging and Message Box rules to include %session.ssl.cert.subject%

The Cert Inspection failed and the client cert subject was neither written to the log event nor the message windows. After that I tried updating the expression to read: * expr { [mcget {session.ssl.cert.subject}] == * }

The Client Inspection rule failed stating it encountered an unexpected value "*". After that I tried updating the expression to read: * expr { [mcget {session.ssl.cert.subject}] conaints ".domainname.com" }

In all attempts the session variable value was not written to the log nor message window.

I also executed sessiondump -allkeys from the command line however nothing was returned.
