код в session.php

function _start()
   {
      //  start session if not startet
      if( $this->_state == 'restart' ) {
         session_id( $this->_createId() );
      }

      session_cache_limiter('none');
      session_start();

      // Send modified header for IE 6.0 Security Policy
      header('P3P: CP="NOI ADM DEV PSAi COM NAV OUR OTRo STP IND DEM"');

      return true;
