CFLOGOUT doesn't log out

If I do the following, the authorized user prints out on both lines.  Appears as if CFLOGOUT isn't working.

<cfoutput>Authorized user: #getAuthUser()#</cfoutput><BR/>

<cflogout>

<cfoutput>Authorized user: #getAuthUser()#</cfoutput><BR/>

The above code is in Logout.cfm, which is called when a logout link is clicked in the application.

Things are setup in the following way.  Digest Authentication is being used with Active Directory and IIS.  Session variables are turned on as well as loginStorage="session".   J2EE session variables are also enabled.

Here is the code, from application.cfc, used to login a user.

<CFFUNCTION name="onRequestStart">
  <CFARGUMENT NAME="targetPage" TYPE="String" REQUIRED=true/>

  <CFLOGIN>               
    <CFLOGINUSER name="#GetAuthUser()#" password="" roles="">
  </CFLOGIN>

</CFFUNCTION>

Thanks in advance,

Mike
