Today I was playing around with blocking the Ad and Popup category. By default uses your default blocking page. This made for an ugly web experience with odd looking parts of the text policy blocking page we have setup. So I made a new rule just for blocking ads and popups. Then you make a new HTTP Deny Page. Call it something like “Ad Block”. Now the trick. Put the below code into that page. Assign the new deny page to the ad block only rule and the result is a nice blank area everywhere you had ads that got blocked.
