Cannot restrict access to external link

Good afternoon mogens.lynnerup@gmail.com,

Thank you for your feedback.
After analysing your report, we verified that an error was indeed being generated when attempting to submit the form if the URL contained a dot. This error has already been resolved, as we have added a new validation that prevents this error in the latest version of our module.

However, our module is not designed to restrict access to external URLs, as it only acts on the URLs of the website on which it is installed, as can be seen in our description.

Therefore, we suggest some possibilities for what you want to do:

• Visual blocking through twig
• Creating a Route subscriber
• Or with a more archaic and less recommended alternative, which would be to create a specific permission for accessing external links. This permission would then have to work in conjunction with custom code that would prevent users from accessing these links.

It should be noted that either of these alternatives will only be effective if accessed through the website itself and will not completely block these links.

Kind regards,
Cláudia Desidério
