Limitations of this tool

  • Sending too many get requests for validating linked resource can get a user’s IP address to get blacklisted or rate limited by the server.
  • Most external URLs can’t be verified to be correct or not because some servers are configured to disallow cross origin requests and also because of CORB protection

Input parameters

  • Hostname: This input parameter is used for identifying the hostname for which a rule will be applied.

  • Whitelisted schemes: This input parameter allows a user to select schemes that must be whitelisted. Whitelisted schemes will not result in an error while checking for broken tags.

  • Excluded URLs: This input parameter allows a user to specify what URLs must be excluded from getting checked. Excluded URLs will be skipped from getting checked by the tool regardless of whether they are valid or not.

  • Highlight Options: Allows a user to specify whether valid links should be highlighted or not. If box is unchecked then valid links won’t be highlighted.
