Accessing external web domains in LockDown Browser

By default, if an exam contains a link to an external web domain, students can view the initial page but all links and navigation from that page are blocked.

With the LockDown Browser Dashboard->"exam"->Modify Settings->Advanced Settings->"Allow access to specific external web domains" option, the setting allows a student to access any page or link within the specified domain. This is useful, for example, to provide access to an e-book during an exam.

To add a site such as a publisher's e-book reader, the instructor enters the "domain" of all the locations including any specific paths. Multiple domains can be entered, separated by commas. Do not include the "http:" or "https:" protocols or any parameters staring at a "?" in the address.

As an example, to access Amazon's Kindle Cloud Reader, the instructor would enter "" along with "" separated by commas into the "Allow access to specific external web domains beta" listing.

You must then also include a link to the whitelisted domain in the quiz question. Without such a link, students will not be able to access that domain.

Once the link is clicked on by the student, that link will open in a second tab and remain open during the exam until the student closes it. If you desire to have the domain open during the entire exam, it's only necessary to place the link in the first question.

If students encounter a "Linked is Blocked ?" while accessing an external domain, it indicates additional domains may need to be added to the external web domains list. Clicking on the "?" will bring up a brief pop-up window showing the URL for the blocked link. The domain listed in the window can be added to the "Allow access to specific external web domains beta" listing.

Please note, e-textbooks and similar resources with digital rights management that requires downloading the book for viewing in an offline app (examples: Kindle, Adobe, Kobo, OverDrive, etc) are not supported. The student will need to locate a supported alternate device (tablet, e-book, etc) or obtain a paper-based edition.
