How to allow http content within an iframe on a https site?

To allow HTTP content within an iframe on a HTTPS site, you can use the following approach:

1. Set the Content-Security-Policy header in the HTTP response to allow loading content from HTTP sources within the iframe. You can set the header with the following value:

1

Content-Security-Policy: frame-ancestors 'self' http://example.com;

Replace http://example.com with the domain from where the HTTP content is loaded.

1. Use the allow attribute in the iframe tag to explicitly allow loading content from HTTP sources. For example:

1

<iframe src="http://example.com" allow="insecure-content"></iframe>

By using these approaches, you can allow loading HTTP content within an iframe on a HTTPS site. However, keep in mind that loading HTTP content within a HTTPS site can pose security risks, so it is recommended to use HTTPS content whenever possible.
