Checks if the link that you entered belongs to a specific site. If it does, returns true, otherwise, false.

Links must be specified in full, including the protocol (http, https, ftp).

The www. subdomain is ignored when checking, meaning that links to and are considered to be the same.

View example in the sandbox.

How to pass a link address:

  • Specify it explicitly as a string.

  • (../operations/work-with-data. dita).

  • Refer to another element using $ref.

  • Use helpers and conditions to get the value.
