APM Session ID not displayed in error page

Replaced the code in Access Policy> Ending Pages> Deny> logout.inc

Brad Parker may correct me, but this seems to be working for me:

var display_session = "%{session.user.sessionid}";
    if(null != display_session) {
      document.getElementById("sessionDIV").innerHTML = '
%[session_id_caption]  ' + display_session + '
';
      document.getElementById("sessionDIV").style.visibility = "visible";
    }

%{session.user.sessionid} pulls the variable for the session ID off the APM directly when the user started the session, rather than from javascript on the local browser as the original script was configured. Might not work in all conditions, but for simple cases it appears to be working.
