Blocked and allowed lists overview
Blocked and allowed lists allow you to easily customize your policies, to ensure they work for your teachers and students.
With Hāpara Filter, you can block entire hosts or domains, or choose to allow/block portions of websites.
Our Youtube allowed/blocked lists give you control over individual videos, entire channels, and categories.
How to configure your blocked/allowed lists
Your Blocked/Allowed lists are found in the Policy Manager tab of your Hāpara Filter Admin Console. You can set up different lists for each of your rules. The configurations below may help you solve common scenarios for setting up your blocked/allowed lists:
Block a subdomain
Simply add foo.example.com to the blocked list. This will allow all traffic to example.com except foo.example.com.
Allow only a subdomain
Simply add example.com to the blocked list and foo.example.com to the allowed list.
Block part of a website
Adding www.example.com/test to the blocked list would block all URLs starting with www.example.com/test.
Block all other streaming media and allow YouTube only
If you would like to block all streaming media except for YouTube, under Policies, check Streaming media and download. The, add “youtube.com” to the allowed list.
The Filter will still apply AI analysis on YouTube contents even though the Streaming media category is blocked.
Allow only selected YouTube videos
If you would like to allow only a select few YouTube videos, under Policies, check the box to block the category Streaming media and download or add “youtube.com” to the blocked list. Then enter the URL(s) of the video(s) into the allowed list. You will be able to select whether to allow this video only, its channel, or its category.
About entering URLs into the block/allow lists
Each blocked or allowed list item is a URL.
- The http:// or https:// part is optional.
- Including "www." before the domain name vs. excluding "www." have different filtering effects: The wildcard * is usually not necessary as we automatically match the webpages hosted under the hostname or URL.
For instance, www.example.com would filter every webpage on www.example.com. However, it won’t filter videos.example.com.
example.com would filter every webpage in the example.com domain, including www.example.com and videos.example.com.
- example.com/foo would filter every sub-webpage of example.com/foo (e.g. example.com/foo/bar), including itself.
If both the accept/block lists have URLs from the same domain, sites will be allowed until reaching the block lists' longest sub-webpage match.
An explanation would be if example.com/foo is in the allowed list and example.com/foo/bar is in the blocked list, example.com/foo would be allowed but example.com/foo/bar would be blocked and any subpages such as example.com/foo/bar/(...) would be blocked.
YouTube videos work the same way, except one is given the options to allow or block individual videos, channels, and categories.
- * can be used in hostnames. Each * would match exactly a component in the hostname between the dots. For instance, *.example.com would match foo.example.com, but not foo.bar.example.com.
Or www.example.* would match www.example.com and www.example.org.
- * itself matches everything. For instance, if you’d like to block all websites except for a few selected ones, just enter * into the blocked list and the allowed websites into the allowed list.
- If the same item appears in both the blocked and allowed lists, Hāpara Filter will allow the identical URLs. That means if example.com/foo/bar is in both the allowed and blocked lists, the Hāpara filter will allow example.com/foo/bar.
Hāpara Filter's approach for social networking, streaming media, and search engine category Sites
For domains that our AI classifies as social networking, streaming media, and search engines, the allow list works a little differently. Even when these aforementioned category-type sites are allowed, the AI still kicks in on these websites because it's just too likely that inappropriate content can come through.
