[opencms-dev] FlexResponse: potentially problematic redirect

[Michael Kraus]

I looked at the OpenCms (6.0.4) sources and this to be the place where the warning log occurs:

[class CmsFlexResponse:604]

             if (LOG.isWarnEnabled()) {
                 if (m_controller.getResponseStackSize() > 2) {
                     // sendRedirect in a stacked response scenario, this may cause issues in some appservers
                     LOG.warn(Messages.get().key(
                         Messages.LOG_FLEXRESPONSE_REDIRECTWARNING_3,
                         m_controller.getCmsResource().getRootPath(),
                         m_controller.getCurrentRequest().getElementUri(),
                         location));
                 }
             }

What does "stacked response scenario" mean, and how do I avoid it?

Any help would be appreciated.

Kind regards,
	Michael Kraus
