请问：在Servlet的run方法中设置了response的setHeader("Host")值，为何在request中用getHeader("Host")无法取出刚刚设置的值！

Question

应该是setHeader("Host","locallost");
getHeader("Host");
要不把代码贴出来

Answer 1

呵呵~~没错！是这样子的！
HttpServletResponse.setHeader("Host", java.net.InetAddress.getByName(HttpServletRequest.getServerName()).getHostAddress() + ":" + HttpServletRequest.getServerPort());
我不管它是用http://hostname:port或者是http://ip:port访问~~我都将它的前面的hostname或ip解析成ip~~然后统一写到头里去！
但在getHeader里就出不来！
