referer/ip

[Miran Cvenkel]

This code returns referer, or ip if there is no referer.
What are the chances that I get wisited by google robot/anything else, and referer comes out as empty string ?
I'm getting empty string into my db.

String  referer = "";

for(Enumeration e = ((HttpServletRequest) request).getHeaderNames(); e.hasMoreElements();)
        {
          headernames += (String)e.nextElement() + ",";
        }
        if (headernames.contains("referer"))
        {
          referer =  ((HttpServletRequest) request).getHeader("referer");
        }
        else
        {
          referer =  "";
        }


        if (referer.equals(""))
        {
          //RETURNS IP ADDRESS OF CLIENT SYSTEM,that is real ip if stuff is behind proxy
          String ip =  ((HttpServletRequest) request).getHeader("X-FORWARDED-FOR");
          //if null, can mean it is not behind proxy
          if(ip == null)
          {
            ip = ((HttpServletRequest) request).getRemoteAddr();
          }
          referer = ip;
        }
