Limiting the External URLs that Can Be Used for Redirection
Use the %validConst% tag in output templates to specify a list of URLs to which an HTML page resulting from the output template can be redirected. By specifying the %validConst% tag, the page can only be redirected to the URLs you specify.
For more information about how to use this tag, see Specifying a List of Permitted URLs for Redirection.
