variable from HTTP_REQUEST to ACCESS_POLICY_AGENT_EVENT

when HTTP_REQUEST { if { [HTTP::uri] contains "username="} { set uri [URI::decode [URI::query [HTTP::uri]]] set urisplit [split $uri "&"] set uname [lindex $urisplit 2] log local0. $uname }

}

when ACCESS_POLICY_AGENT_EVENT { if { [ACCESS::policy agent_id] eq "getusername" } { ACCESS::session data set session.temp.username $uname } }

I am assigning session.temp.username to session.logon.last.username using variable assignment

The bit that is not working is assignment of $uname to ACCESS::session data set session.temp.username
