We’ve been trying to implement a site with a http home page, but https everywhere else. In order to do this we hit the rather big snag that our login form, in a lightbox, would need to fetch a https form using ajax, embed it in a http page and then (possibly) handle the form errors, still within the lightbox.
In the end we gave up and just made the whole site https, but I’m sure I’ve seen a login-in-a-lightbox implementation on other sites, though can’t find any examples now I want to.
Can anyone give any examples of sites that have achieved this functionality, or explain how/why this functionality can/can’t be achieved.
The Same Origin Policy prevents this. The page is either 100% HTTPS or it’s not. The Same Origin Policy sees this as a “different” site if the protocol is not the same.
A “lightbox” is not different than any other HTML – it’s just laid out differently. The same rules apply.
