    The benefits of CORS are:. Talha Saqib Founder of Retrology. It will get flagged in a security audit. Thanks for your help with this and your detailed answer. Restart the server and resend the message by clicking the Put v2 button. Modified 5 years, 2 months ago. Authentication providers, such as Okta, need to handle cross-domain requests to their authentication servers and API servers.

    Probable Cause: Cross Origin Resource Sharing (CORS) headers not passed with the static content hosted on Salesforce B2C Commerce. Resolution: Salesforce B2C.CORS has several layers.

    This polling request is failing because the request is originating from a different domain. For e.g. you can see that the Origin header is set to “https://naRequired cookies are necessary for basic website functionality.

    If a browser that supports CORS makes a request to an origin in the allowlist, Salesforce returns the origin in the Access-Control-Allow-Origin HTTP header.View State Tab.

    I am facing cross domain error on ajax request in javascript No 'Access-Control-Allow-Origin' header is present on the requested.If the domain specified in the response header matches the domain of the web page, specified in the Origin request header, then the browser will not block the response being received by JavaScript.

    has been blocked by CORS policy It is possible that the component will not load and a 'CORS' (Cross-Origin Resource Sharing) Error will.When checked in cors log file no error or issue was detected and also when checked via curl commands we can see the header file present for the domain, but somehow when page is loading that header is not present.

    Alternatively, your React developer could use the server as a proxy instead of directly connecting to Salesforce.
