I would be nice to have the BaseXML redirecting-code in a util-class
--------------------------------------------------------------------

                 Key: RF-7984
                 URL: https://jira.jboss.org/jira/browse/RF-7984
             Project: RichFaces
          Issue Type: Feature Request
    Affects Versions: 3.3.2.GA
            Reporter: Andreas Höhmann
            Priority: Minor

I wrote a special spring security entry point to handle missing authentication *after* a a4j-request:

  /**
   * {@inheritDoc}
   */
  @Override
  protected void sendRedirect(final HttpServletRequest theRequest, final HttpServletResponse theResponse,
      final String theUrl) throws IOException {
    if (!isAjaxRequest(theRequest)) {
      LOG.debug("normal redirect to " + theUrl);
      super.sendRedirect(theRequest, theResponse, theUrl);
    } else {
      LOG.debug("ajax redirect to " + theUrl);
      final FilterServletResponseWrapper servletResponseWrapper = new FilterServletResponseWrapper(theResponse);
      final Writer output = resetResponse(theResponse, servletResponseWrapper, "redirect");
      theResponse.setHeader(AjaxContainerRenderer.AJAX_LOCATION_HEADER, theUrl);
      // For buggy XmlHttpRequest realisations repeat headers in
      // <meta>
      output.write("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n"
          + "<html xmlns=\"http://www.w3.org/1999/xhtml\"><head>" + "<meta name=\""
          + AjaxContainerRenderer.AJAX_FLAG_HEADER + "\" content=\"redirect\" />" + "<meta name=\""
          + AjaxContainerRenderer.AJAX_LOCATION_HEADER + "\" content=\"" + theUrl + "\" />" + "</head></html>");
      output.flush();
      theResponse.flushBuffer();
    }
  }

Currently i'm must copy the redirecting-code from org.ajax4jsf.webapp.BaseXMLFilter to reuse it.
It would be nice to have a "A4JResponseUtils" with this methods:
- boolean isAjaxRequest(final ServletRequest request)
- void sendRedirect(final HttpServletRequest theRequest, final HttpServletResponse theResponse, final String theUrl)

The advantage of such a utils-class would be a always compatibly thirdparty code (integration code), if the redirecting-code changes in a4j my code should still work :D
