ℹ️ About CORS

Cross-Origin Resource Sharing (CORS) is a security mechanism that allows or restricts web applications from making requests to a different domain than the one serving the web page.

Common CORS Headers:

  • Access-Control-Allow-Origin — Specifies which origins can access the resource
  • Access-Control-Allow-Methods — Allowed HTTP methods
  • Access-Control-Allow-Headers — Allowed request headers
  • Access-Control-Allow-Credentials — Whether credentials (cookies) are allowed
  • Access-Control-Max-Age — How long preflight results can be cached
  • Access-Control-Expose-Headers — Headers the browser can access

Note: Due to browser security restrictions, some CORS tests may be limited. For comprehensive testing, use the generated cURL command in your terminal.
