Cross-origin resource sharing (CORS)

Cross-origin resource sharing (CORS) is a mechanism that allows restricted resources on a web page to be accessed from another domain outside the domain from which the first resource was served. CORS also relies on a mechanism by which browsers make a “preflight” request to the server hosting the cross-origin resource, in order to check that the server will permit the actual request. In that preflight, the browser sends headers that indicate the HTTP method and headers that will be used in the actual request. For security reasons, browsers restrict cross-origin HTTP requests initiated from scripts. For example, fetch() and XMLHttpRequest follow the same-origin policy. This means that a web application using those APIs can only request resources from the same origin the application was loaded from unless the response from other origins includes the right CORS headers.

Resource types

this easy application contain 3 branches. master branch include api and project branch include windows form application for connect to api. and project2 branch include asp.net web application to connect the api. to run to this application, you require to IIS manager activation and publish api with this. and you have to install CORS inside your api project. for prevent to this error: Access to XMLHttpRequest at 'http://xxx/api' from origin 'https://yyy' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
