I would like to delete an entire session. Cflogout simply ends the session, but the variables remain on the server.

Here is my code I am using to view active sessions (basically shows a table of all users currently logged in)

<!--- Dump all session scopes --->
      <table width="95%" align="center" cellspacing="0" cellpadding="0" bgcolor="#EBE9E9">
            <TR bgcolor="#999999">
                  <TD align="left" valign="top"><img src="../images/topleft.gif"></TD>
                  <TD colspan="5" align="center"><B>Currently Logged In Users</B>&nbsp;<I>(Click to log user out)</I></TD>
                  <td align="right" valign="top"><img src="../images/topright.gif"></td>
            </TR>
            <TR>
                  <TD>&nbsp;</TD>
                  <TD><B>Cust Code</B></TD>
                  <TD><B>User Name</B></TD>
                  <TD><B>Real Name</B></TD>
                  <TD><B>Login Date</B></TD>
                  <TD><B>IP</B></TD>
                  <TD>&nbsp;</TD>
            </TR>
      
      <cfscript>
      session.test = true;
      tracker = createObject("java", "coldfusion.runtime.SessionTracker");
      mySession = tracker.getSessionCollection( application.applicationName );
      
      for (keyname in mySession) {
         WriteOutput("<TR onclick=""parent.Action.location.href = 'action.cfm?ToDo=KillSession&Session=" & keyname & "';"" onMouseover=""this.style.backgroundColor='##FF9999';"" onMouseout=""this.style.backgroundColor='##EBE9E9';"" style=""cursor:pointer; background-color : ##EBE9E9;""><TD>&nbsp;</TD><TD>" & mySession[keyname].custcode & "</TD><TD>" & mySession[keyname].username & "</TD><TD>" & mySession[keyname].name & "</TD><TD>" & DateFormat(mySession[keyname].lastlogin, "MM/DD/YYYY") & "&nbsp;" & TimeFormat(mySession[keyname].lastlogin, "HH:MM") & "</TD><TD>" & mySession[keyname].ip & "</TD><TD>&nbsp;</TD></TR>");
      }
      </cfscript>
      </table>


On my page action.cfm, for the ToDo='KillSession', I want to be able to delete the entire structure for the given users session.

My application name is 'Secure', and the key looks like this:   secure_84301870811097497028343


My current code looks like this:  But it appears to do nothing at all, not even error out:

                <cfcase value="KillSession">
                  Deleting session <cfoutput>#URL.Session#</cfoutput><BR><cfflush>
                  
                  <cfset a = StructDelete(session, URL.Session)>
                  Done.<cfflush>
            </cfcase>

Can anyone tell me what I am doing wrong???
