Thank you for posting your query on Microsoft Q&A.
You can define configuration in the staticwebapp.config.json file, which controls the following settings:
https://learn.microsoft.com/en-us/azure/static-web-apps/configuration
- Routing
- Authentication
- Authorization
- Fallback rules
- HTTP response overrides
- Global HTTP header definitions
- Custom MIME types
- Networking
This file is used to define the configurations for your app, including custom headers.
Here's an example of how to add a Content Security Policy header in the staticwebapp.config.json
file:
{
"globalHeaders": {
"content-security-policy": "default-src https: 'unsafe-eval' 'unsafe-inline'; object-src 'none'",
"Access-Control-Allow-Origin": "*",
"X-Frame-Options": "SAMEORIGIN",
"X-Permitted-Cross-Domain-Policies": "none",
"Referrer-Policy":"no-referrer",
"X-Content-Type-Options": "nosniff",
"Permissions-Policy": "autoplay=()"
}
}
