I have a iframe. This iframe open a domain. But how can i protect this iframe. When i go to this iframe i get this url:
http://………nl/rganisatie/werken_bij/vacatures?u=http%3A//vacatures.wrij.nl/
But no can change people the domain name of the iframe. When you change vacatures.wrij.nl/ to a other website. The iframe open a other domain / website. I would protect this.
How can i make with javascript. That the iframe open only one domain?
Thanks!
