I have a facebook page tab iframe and would like to access the browser url in order to get the current facebook page url.
I know it’s not possible to use a javascript that interacts with the parent frame because of browser security issues.
An approach that didn’t work for all browsers was to read the HTTP_REFERER header from the request.
Is there a better way?
I hope this is impossible at all. Otherwise it will be a security issue, likely to be closed.
You should not write code depending on compromising other users.
