Best way to deny access to URL

Hi xbox360, I had a similar issue where I wanted to apply an action based on the URL. I did this via the ASM policy, when filtering by referrer I needed to mark as 'do nothing' and then the URL specified from the referrer specified passed through. In your case you want to block connections with a similar rule. My case is noted here, I hope something there may help: https://devcentral.f5.com/questions/allowed-url-however-its-still-being-blocked?
