Re: Excluding a domain in snort rule

["Joel Esler (jesler)" <jesler () cisco com>]

I would suggest disabling that rule all together.  That pattern hasn’t been used in years.

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

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

Thanks,
John
