RESHEADER ACCESS CONTROL ALLOW ORIGIN SERIAL

If the request is not preflighted, then the request will include credentials, and if the server's response does not set the Access-Control-Allow-Credentials header to true, the browser reports a network error.If the server's response to the preflight request sets the Access-Control-Allow-Credentials header to true, then the real request will include credentials: otherwise, the browser reports a network error. If the request is preflighted, then the preflight request does not include credentials.If the client has asked for credentials to be included: Using XMLHttpRequest, by setting the XMLHttpRequest.withCredentials property to true.Using fetch(), by setting the credentials option in the Request() constructor to 'include'.By default, these credentials are not sent in cross-origin requests, and doing so can make a site vulnerable to CSRF attacks.Ī client can ask that credentials should be included in cross-site requests in one of two ways: The Access-Control-Allow-Credentials response header tells browsers whether the server allows cross-origin HTTP requests to include credentials.Ĭredentials are cookies, TLS client certificates, or authentication headers containing a username and password.
