Unable to create .stat file

Hi,

I am trying to implement dispatcher flush. Hear is my cache properties. In my cache folders are getting created. But I am unable to found any .stat file in any folder. Any reason why this happening? 

/cache
      {
      # The docroot must be equal to the document root of the webserver. The
      # dispatcher will store files relative to this directory and subsequent
      # requests may be "declined" by the dispatcher, allowing the webserver
      # to deliver them just like static files.
      /docroot "D:/Apache2.2/cache"
      
      # Sets the level upto which files named ".stat" will be created in the 
      # document root of the webserver. When an activation request for some 
      # page is received, only files within the same subtree are affected 
      # by the invalidation.
      
      /statfileslevel "1"
      
      # Flag indicating whether to cache responses to requests that contain
      # authorization information.
      /allowAuthorized "0"
      
      # Flag indicating whether the dispatcher should serve stale content if
      # no remote server is available.
      #/serveStaleOnError "1"
      
      # The rules section defines what responses should be cached based on
      # the requested URL. Please note that only the following requests can
      # lead to cacheable responses:
      #
      # - HTTP method is GET
      # - URL has an extension
      # - Request has no query string
      # - Request has no "Authorization" header (unless allowAuthorized is 1)
      /rules
        {
        /0000
          {
          # the globbing pattern to be compared against the url
          # example: *             -> everything
          #        : /foo/bar.*    -> only the /foo/bar documents
          #        : /foo/bar/*    -> all pages below /foo/bar
          #        : /foo/bar[./]* -> all pages below and /foo/bar itself
          #        : *.html        -> all .html files
          /glob "*"
          /type "allow"
          }
        }
        
      # The invalidate section defines the pages that are "invalidated" after
      # any activation. Please note that the activated page itself and all 
      # related documents are flushed on an modification. For example: if the 
      # page /foo/bar is activated, all /foo/bar.* files are removed from the
      # cache.
      /invalidate
        {
        /0000
          {
          /glob "*"
          /type "deny"
          }
        /0001
          {
          # Consider all HTML files stale after an activation.
          /glob "*.html"
          /type "allow"
          }
        /0002
          {
          /glob "/etc/segmentation.segment.js"
          /type "allow"
          }
        /0003
          {
          /glob "*/analytics.sitecatalyst.js"
          /type "allow"
          }
        }

      # The allowedClients section restricts the client IP addresses that are
      # allowed to issue activation requests.
      /allowedClients
        {
        # Uncomment the following to restrict activation requests to originate
        # from "localhost" only.
        #
        #/0000

        #  /glob "127.0.0.1"
        #  /type "allow"
        #  }
        }
        
      # The ignoreUrlParams section contains query string parameter names that
      # should be ignored when determining whether some request's output can be
      # cached or delivered from cache.
      #
      # In this example configuration, the "q" parameter will be ignored. 
      #/ignoreUrlParams

      #  /0001 { /glob "*" /type "deny" }
      #  /0002 { /glob "q" /type "allow" }
