Maybe it's me, but what is the advantage of having a web site/page listed with multiple categories? I am allowing Education/Reference and blocking Online shopping and have a number of teaching web sites being blocked because of the multiple categories listed on one page. Outside of whitelisting any ideas on how to solve this or will this be addressed?
The advantage is in better fine-tuning, for example a news website which also hosts streaming media could be categorized as both "general news" and "internet radio/tv". If you allow news but block streaming media, this added granularity can give you better control over what content is allowed on your network.
I can understand why some may like the feature as you describe it, but many sites that educators use are dual listed when only one page may have the shopping feature so the entire site is now blocked. We agree to disagree, that said, is there a way other than white listing sites to get around this?
