       # with Firefox Firebug, Firephp and Yslow benchmark tests.
   
       # Create the ETag (entity tag) response header field
       #FileETag MTime Size
   
       # Remove the ETag (entity tag) response header field
       Header unset ETag
       FileETag none
   
       <IfModule mod_expires.c>

       ```
