adblock on web filter

[Darkstar]

Hi,

Im having a problem with one site, when I have web filtering enabled, it keeps denying access claiming that adblock is used. Thats exacly how some sites behave, when adblock addons are on. What i understand is, that this site uses referal links in its html code, and fortigate block those, thus this adblock note.

Making a new policy for this site wont work, because I dont know which urls inside are being blocked. Even if I knew, that can change in 5 minutes. How can I exempt this site and underlying links from web filtering ?
