Question

I’m trying to implement a 301 redirect from within JSF but when I firebug it I always see a 302 being executed. Would someone be able to show me how to alter the method below to accomplish a 301?

/**
 * Redirect to specified destination url
 *
 * @param destination
 */
public static void permanentRedirect(String destination) {
    final ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();

    try {
        HttpServletResponse response = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse();
        response.setStatus(HttpServletResponse.SC_MOVED_PERMANENTLY);

        if (!response.isCommitted()) {
            externalContext.redirect(destination);
        }
    } catch (IOException e) {
        LOGGER.debug("Could not redirect to " + destination);
    }
} 

Answer 1

You shouldn’t invoke externalContext.redirect(destination). It will override the status to 302. You should manually set the Location header and complete the response.

externalContext.setResponseStatus(HttpServletResponse.SC_MOVED_PERMANENTLY);
externalContext.setResponseHeader("Location", destination);
facesContext.responseComplete();
