code: public static String getScopedSessionAttrName( String attrName, HttpServletRequest request )
      {
          String requestScopeParam = request.getParameter( SCOPE_ID_PARAM );
          
          if ( requestScopeParam != null )
          {
              return getScopedName( attrName, requestScopeParam );
          }
          
          ScopedRequest scopedRequest = unwrapRequest( request );
          return scopedRequest != null ? scopedRequest.getScopedName( attrName ) : attrName;
      }
docs: If the request is a ScopedRequest, this returns an attribute name scoped to
  that request's scope-ID; otherwise, it returns the given attribute name.
