CORS headers should be properly defined in respect of trusted origins for private and public servers. #8406; OAuth2 (oauth2) Parsing Media Queries. WebCross-Origin Resource Sharing (CORS) is an HTTP-header based mechanism that allows a server to indicate any origins (domain, scheme, or port) other than its own from which a browser should permit loading resources. Web browsers automatically use the null origin in some circumstances, such as after a CORS request has been redirected by the target resource, or when this request has been sent from a specific resource type (for example, from an iframe, or using a local file). ## Description: An HTML5 cross-origin resource sharing (CORS) policy controls whether and how content running on other domains can perform two-way interaction with the domain that publishes the policy.
