https http 세션 공유가 안된다....

인터넷에 검색된 필터도 적용하는데 안된다...

왜그런지 모르지만 로그인후 세션 생성하기전 request.getSession().invalidate(); 을 실행해주니 정상적으로 필터에서

새로운 쿠키가 적용 되었다...

아래는 필터

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class HttpsFilter implements Filter {

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

HttpsRequestWrapper httpsRequest = new HttpsRequestWrapper((HttpServletRequest) request);

httpsRequest.setResponse((HttpServletResponse) response);
chain.doFilter(httpsRequest, response);
}

public void destroy() {
// TODO Auto-generated method stub
}

public void init(FilterConfig arg0) throws ServletException {
// TODO Auto-generated method stub
}
}

import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

public class HttpsRequestWrapper extends HttpServletRequestWrapper {

private HttpServletResponse response = null;

public HttpsRequestWrapper(HttpServletRequest request) {
super(request);
}

public void setResponse(HttpServletResponse response) {
this.response = response;
}

public HttpSession getSession() {
  HttpSession session = super.getSession();
  processSessionCookie(session);
  return session;
}

public HttpSession getSession(boolean create) {
  HttpSession session = super.getSession(create);
  processSessionCookie(session);
  return session;
}

private void processSessionCookie(HttpSession session) {
if (null == response || null == session)
return;

Object cookieOverWritten = getAttribute("COOKIE_OVERWRITTEN_FLAG");

if (null == cookieOverWritten && isSecure() && isRequestedSessionIdFromCookie() && session.isNew()) {

   Cookie cookie = new Cookie("JSESSIONID", session.getId());
   cookie.setMaxAge(-1);
   String contextPath = getContextPath();

   if ((contextPath != null) && (contextPath.length() > 0)) {
    cookie.setPath(contextPath);
   } else {
    cookie.setPath("/");
   }
   //cookie.setSecure(false);
   response.addCookie(cookie);

setAttribute("COOKIE_OVERWRITTEN_FLAG", "true");
}
}
}

web.xml -> 최상위

<filter>
  <filter-name>httpsFilter</filter-name>
  <filter-class>com.project.common.filter.HttpsFilter</filter-class>
</filter>
<filter-mapping>
  <filter-name>httpsFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

2일정도 개삽질...
