I have a site that, by necessity, needs to load into an iFrame on another site. Part of the site is a Channel Form however this page won't load into the iFrame because the X-Frame-Options header is being set. I see the addition of this header was an update in 2.5.
Does anyone know how I can stop this header from being set? I don't think I have any option other than to modify the Core but I can't find where it's being set.
