Dear experts here:

I am working on an issue raised by our frontend web developer for his angular 2 application. The application is hosted on an nginx server with CORS configured. The Chrome throws an error and says multiple values for CORS. I am attaching the nginx configuration file in the attachment.



XMLHttpRequest cannot load http://dev-cms.avery.com/api/content/render/false/type/json/query/type:content%20+markerProductGroup-marker:6a12d922-ea1d-4a1b-8c46-3e3fbb9bcd5c. The 'Access-Control-Allow-Origin' header contains multiple values '*, *', but only one is allowed. Origin 'http://localhost:4200' is therefore not allowed access.
