The site is https, it has an iframe, what should I do to load the http site in it?

Question

Web development

The site is https, it has an iframe in which the http site should be loaded.
Sites in this iframe are loaded differently, both https and http, access to their content is not required, only to be displayed.

What do you advise?

Answer 1

Proxy through your server and give through https. Or raise https where you load the iframe from.
What's the point of htpts otherwise, if the iframe will be loaded via http? iframe traffic will be intercepted and replaced. In particular, you can replace the entire page in this case - that's why you can't embed http elements on https pages.
