防盗链就是防止别人的网址代码里面盗用服务器的图片,文件,视频等相关资源
如果别人盗用网站的这些静态资源,明显的是会增大服务器的带宽压力
所以作为网站的维护人员,要杜绝我们服务器的静态资源被其他网站盗用
%{}HTTP_REFERER}: 浏览header中的链接字段,存放一个链接的URL,代表是从哪个链接访问所需的网页
!^: 不以后面的字符串开头
.*$: 以任意字符结尾
NC: 不区分大写
R:强制跳转
RewriteEngine On: 打开网页重写功能
RewriteCond: 设置匹配规则
RewriteRule: 设置跳转动作
如果相应变量的值匹配所设置的规则,则逐条向下处理;如果不匹配则往后的规则不在匹配
