# 后端response 302时 tomcat header中location的host是http://192.168.1.62:8080
# 因为tomcat收到的请求是nginx发过去的, nginx发起的请求url host是http://192.168.1.62:8080
# 设置为default后，nginx自动把响应头中location host部分替换成当前用户请求的host部分
# 网上很多教程将此值设置成 off，禁用了替换，
# 这样用户浏览器收到302后跳到http://192.168.1.62:8080，直接将后端服务器暴露给浏览器
# 所以除非特殊需要，不要设置这种画蛇添足的配置
