#1)实现301跳转
#需求1.etiantian.org -->nginx.etiantian.org （301）
#(short_dom为自定义名称 hdr函数包含Host -i(不区分大小写) 匹配etiantian.org ）
acl short_dom hdr(Host) -i etiantian.org
#prefix 前缀跳转 保证访问http://etiantian.org/a.html能够跳转到http://nginx.etiantian.org/a.html
redirect prefix http://nginx.etiantian.org code 301 if short_dom
