static final int ALLOW_DIRECT_INCLUDE

    Used with getFeature(int) to indicate the extendlet can be included directly without going thru Web container.
    In other words, if getFeature(ALLOW_DIRECT_INCLUDE) is true and a corresponding page is included, then service(jakarta.servlet.http.HttpServletRequest, jakarta.servlet.http.HttpServletResponse, java.lang.String) will be invoked directly (rather than calling RequestDispatcher's include method.
