Cross Origin Resource Sharing (CORS) is a W3C standard that allows a server to relax the same-origin policy. Using CORS, a server can explicitly allow some cross-origin requests while rejecting others. CORS is safer and more flexible than earlier techniques such as JSONP.

Configure the Cross-origin resource sharing to use:

##On the back-end:

  "Cors": {
    "Origins": "*",
    "Methods": "*",
    "Headers": "*"
  },

Or

  "Cors": {
    "Origins": "http://example.com,http://www.contoso.com",
    "Methods": "GET,POST,HEAD",
    "Headers": "accept,content-type,origin,x-custom-header"
  },

Where:

• [Cors.Origins]: The domains enabled to used by the microservice.
• [Cors.Methods]: The methods enabled to used by domain external of the microservice.
• [Cors.Headers]: The conteainers headers enabled to used by the microservice.
