Excluding a domain in snort rule

[John G <drterdnugget () gmail com>]

I have this alert that is triggering on a legitimate site.

EXPLOIT-KIT Angler exploit kit news uri structure (1:38439:2)


alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"EXPLOIT-KIT
Angler exploit kit news uri structure"; flow:to_server,established;
content:"/news/"; fast_pattern; http_uri; content:"/"; within:5;
distance:1; http_uri; content:"/"; within:5; distance:1; http_uri;
content:"/"; within:5; distance:1; http_uri;
pcre:"/^\/news\/([0-9]+\/){3}[0-9]{5,10}(\.html)?$/U"; metadata:impact_flag
red, policy max-detect-ips drop, service http; classtype:trojan-activity;
sid:38439; rev:2; )


It is triggering because of this site: http://www
[.]wenxuecity[.]com/news/2017/06/06/6293116.html

How could we go about whitelisting that by editing the Snort rule?

Thanks,
John
