So, for everything to work correctly, it's better to specify explicitly the allowed origins. It's also possible to declare the list as "*" (a "wildcard") to say that all are allowed.īut that will only allow certain types of communication, excluding everything that involves credentials: Cookies, Authorization headers like those used with Bearer Tokens, etc. ![]() In this case, it would have to include for the frontend to work correctly. To achieve this, the backend must have a list of "allowed origins". Then, the browser will send an HTTP OPTIONS request to the backend, and if the backend sends the appropriate headers authorizing the communication from this different origin ( then the browser will let the JavaScript in the frontend send its request to the backend. So, let's say you have a frontend running in your browser at and its JavaScript is trying to communicate with a backend running at (because we don't specify a port, the browser will assume the default port 80).
