Cross Domain Security

We strongly recommend that you implement the HTTP security header Cross-Origin-Opener-Policy with the value of same-origin on your website. This header helps to protect against a variety of potential security issues, including cross-site attacks and data breaches, by isolating your site from other origins sharing the same browsing context.

Implementing this header is critical for:

Security: Ensuring that your web pages are isolated from potentially harmful third-party content.
Compatibility: Making sure that [Your Product] works seamlessly within your website without any security conflicts.
Performance: Allowing your website to better utilize modern web features that improve load times and user experience.

Implementation examples

  • Example of how to set the header in an HTTP response:

    Header set Cross-Origin-Opener-Policy “same-origin”
  • For Nginx servers, add this line to your site configuration:
    add_header Cross-Origin-Opener-Policy same-origin;
