-When you visit a website (i.e <http://catwebsites.com>), the browser issues a request to the server on which the webiste (catwebsites.com) is hosted. The response sent by the server is an HTML file that may contain one or more references to external assets/resources hosted either on the same server that <i>catwebsites.com</i> is hosted on or a different website. When the browser sees reference(s) to a URL in the source HTML, it issues a request. If the request is issued using the URL that the source HTML was fetched from, then the browser processes the response without any issues. However, if the resource is fetched using a URL that doesn't share the same origin(scheme, host, port) as the source HTML, the browser will have to check the `Access-Control-Allow-origin` response header. If it contains `*` or the URL of the source HTML, the browser will process the response, otherwise the browser will refuse to process it and throw an error.
