refresh iframe's parent from within iframe in https
I have a page A and inside it I have an iframe B.
B points to another php file that shows a form (so basically in the iframe we see a form).
When I submit the form, I call to another page C that verifies the fields of the form and if they are ok I redirect to page X, if not I redirect to page Y.
The problem is that I see page X and Y inside the iframe, and I want to see them in the parent page.
Can you help me with this?
