一般网站为了防止资源被外部链接所盗用，都会使用防盗链来进行处理。思路就是判断请求的域名 如下一个相对完全的示例：

#VHOST: x.abc.com
server {
listen 80;
server_name x.abc.com;
charset utf-8;
access_log off;
location / {
return 404;
}
location /themes/ {
alias C:/abc/abc_Web/themes/;
valid_referers none blocked server_names abc.com *.abc.com *.abc.net;
if ($invalid_referer) {
return 403;
}
if ($document_uri ~ "^/themes/(default|img\/(icon|upload))/.*") {
break;
}
if ($document_uri ~ "^/themes/js/(app|widgets)/.*"){
break;
}
}
location /game/ {
alias C:/abc/abc_Web/game/;
valid_referers none blocked server_names abc.com *.abc.com *.abc.net;
if ($invalid_referer) {
return 403;
}
}
location /images/ {
alias C:/abc/abc_Web/images/;
}
}

这段代码的意思是：
listen 80; 监听的端口为80
server_name x.abc.com; 服务器名称为x.abc.com
charset utf-8; 字符集编码为utf-8
access_log off; 不记录访问log日志
location / {
return 404;
}
不允许直接访问根目录
http://x.abc.com/themes/ 将访问指向本地 C:/abc/abc_Web/themes/;
valid_referers none blocked server_names abc.com *.abc.com *.abc.net;
上面这段就是重点，valid_referers none 阻止referers，排除referers为abc.com *.abc.com *.abc.net的域名
然后就是验证了：$invalid_referer
if ($invalid_referer) {
return 403;
}
满足条件则返回403
可以使得正则匹配指定的资源，如.gif或.jpg、.swf、.mp3结尾的资源，还有就是判断其host..
