# 預設值default，
# 後端response 302時 tomcat header中location的host是http://192.168.1.62:8080
# 因為tomcat收到的請求是nginx發過去的, nginx發起的請求url host是http://192.168.1.62:8080
# 設定為default後，nginx自動把響應頭中location host部分替換成當前使用者請求的host部分
# 網上很多教程將此值設定成 off，禁用了替換，
# 這樣使用者瀏覽器收到302後跳到http://192.168.1.62:8080，直接將後端伺服器暴露給瀏覽器
# 所以除非特殊需要，不要設定這種畫蛇添足的配置
