HttpServletResponse sendRedirect permanent

Question

This will redirect a request with a temporary 302 HTTP status code:

HttpServletResponse response; response.sendRedirect("http://somewhere"); 

But is it possible to redirect it with a permanent 301 HTTP status code?

Answer 1

You need to set the response status and the Location header manually.

response.setStatus(HttpServletResponse.SC_MOVED_PERMANENTLY); response.setHeader("Location", "http://somewhere/"); 

Setting the status before sendRedirect() won't work as sendRedirect() would overridde it to SC_FOUND afterwards.
