Web Limiting allows teachers to control which websites students can access during a LanSchool Air class.
You can use Web Limiting to:
Web Limiting settings are configured separately for each class.
Web Limiting is designed to control website access based on website addresses (URLs). It is not a general-purpose browser, application, extension, or AI-service blocking tool.
If your organization needs to prevent students from using browser extensions, AI tools, private browsing, or other browser/application features, use your organization's device management, browser management, or application control policies.
Web Limiting requires the LanSchool Air browser extension on the student's device. LanSchool Air supports Google Chrome, Microsoft Edge and Safari.
The browser extension must be installed and enabled for Web Limiting restrictions to be applied.
If you are experiencing problems with Web Limiting, see Troubleshooting Web Limiting.
Important: Web Limiting does not manage or block browser extensions. The LanSchool Air browser extension is required for Web Limiting to function; however, Web Limiting itself cannot be used to disable other browser extensions.LanSchool Air provides three Web Limiting options:
Use Restrict All Websites when students should not have access to websites.
Example: Prevent internet access during a test or classroom activity.
Use Block Only when students should be able to browse the internet normally except for specific websites you want to block.
Example: Block YouTube, gaming websites, or other distracting websites during class.
Use Allow Only when students should be able to access only specific websites.
Example: During a test, allow students to access only the testing website and approved reference materials.
Any website that is not included in the Allow Only list will be blocked.



*) as a wildcard when adding websites to a Block Only or Allow Only list.Wildcards can be useful when you want to include multiple pages or variations of a website.
Block an entire website:
https://*youtube.com/
This blocks YouTube pages that match the pattern.
Block websites containing a specific word:
https://*.*games*
This blocks URLs containing the word games.
Allow websites containing a specific word:
https://*.*london*
This allows URLs containing the word london.
Allow a specific section of a website:
https://en.wikipedia.org/wiki/Lenovo*
This allows URLs matching the specified Lenovo Wikipedia section.

For example, a student may start on an organization's Student Information System (SIS) website and then be redirected to a different school domain. If the redirected domain is not included in the Allow Only list, it may be blocked.
After configuring the Web Limiting settings:
To stop restricting student websites:
Web access will return to normal for the students selected.
If a Web Limiting Allow Only or Block Only list is missing, appears empty, or suddenly appears to have been reset, first confirm that the class still exists.
If the class has not been deleted, the Web Limiting list may still be available but not displaying correctly in the browser.
Try the following steps:
Important: Do not delete the class to try to resolve a missing Web Limiting list. Web Limiting lists cannot be recovered after the associated class is deleted.
If the class still exists and the Web Limiting list remains missing after refreshing the browser and clearing the browser cache and cookies, contact LanSchool Air Support for assistance.
If the class was deleted, the Web Limiting lists associated with that class cannot be recovered.
For more information, see Web Limiting Lists and Class Deletion.
The availability of a Web Limiting list depends on how the class was created.
Web Limiting lists created in a manually created class will remain available as long as the class itself is not deleted.
If the manually created class is deleted, the Web Limiting lists associated with that class cannot be recovered.
Web Limiting lists created in an imported class are associated with that class.
This includes classes imported from:
If an imported class is removed from the Student Information System (SIS) or the source system and the class is subsequently removed from LanSchool Air, any Web Limiting lists associated with that class will also be deleted.
Web Limiting lists cannot be recovered after the associated class has been deleted.
Important: If you need to keep a Web Limiting list, make sure the associated class is not deleted. It's recommended to build the limit web list in a manually created class.
If Web Limiting is enabled but students can still access restricted websites:
