redirect and transfer of header to another URL

[aliasnash]

Hi all!

There is a controller that redirects user to a specific Url:

	@RequestMapping(value = "/goto", method = RequestMethod.GET)
	public String redirectToSite(ModelMap model, HttpServletRequest request, HttpServletResponse response)
	{
		String url = "http://www.site.ru";
		
		response.addHeader("transfer_header", "whata_is_it");
		
		return "redirect:" + url;
	}

The problem is that after the redirect to the site "http://www.site.ru", I can't find my header "transfer_header"
Where is it?
How can I do the transfer of header correctly?

Thanks in advance for your help.
