请教专业人士：nginx反向代理网站图片无法显示

[uniway]

小弟是一个牙医，最近业余时间开始迷恋nginx，做了一个简单的反向代理nytimes，但是图片无法显示。对方站的图片在graphics8.nytime.com，是akamai的cdn，我猜测nginx反代时直接解析对方ip，而直解析后的ip是无法访问akamai内容的，因此无法打开这些图片。不知道是不是这样，有没有什么解决办法呢？


server
{
listen 80;
server_name news.xxx.org *.news.xxx.org;

if ( $host ~* (.*)\.(.*)\.(.*))
{
set $domain $1;
}
location /
{
proxy_pass http://170.149.172.130;

proxy_set_header Host $host;

proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
subs_filter 'www.nytimes.com' 'news.xxx.org' ig;
subs_filter 'graphics8.nytimes.com' 'graphics8.news.xxx.org' ig;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Accept-Encoding ""; # GZIP
}
access_log off;
}
