I have production server say ServerA in which I have deployed my angular application. I am deployed it in Tomcat . Now I have another server which is serving backend calls say ServerB now when my angular application running on ServerA makes calls to ServerB. It is giving CORS issue.
Please note:- I am using https protocol
Any Idea how to make such calls
ServerB needs to set response headers. https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Allow-Origin
Two options
Server A and have a communication b/w Server A and Server B
See : Smiley's HTTP Proxy Servletor
Server B which accepts requests from Server A angular application
See : Access-Control-Allow-OriginThe server needs to handle the origin. Here ServerB should accept request from ServerA and should sent header response as:-
Access-Control-Allow-Origin: http://ServerA.com Access-Control-Allow-Credentials: true Access-Control-Expose-Headers: FooBar Content-Type: text/html; charset=utf-8
I recommend to go this blog https://www.html5rocks.com/en/tutorials/cors/ for better understanding. This explains clearly on handling simple and not so simple requests.
