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 utilise modern web features that improve load times and user experience.
Implementation examples
- Example of how to set the header in an HTTP response:
1-http
Cross-Origin-Opener-Policy: same-origin - For an Apache server, you can add the following line to your .htaccess file:
2-apache
Header set Cross-Origin-Opener-Policy “same-origin” - For Nginx servers, add this line to your site configuration:
