Steps to reproduce

User enters the website URL https://service.app.com
It gets redirected to https://authentication.app.com and once when the user enters the credentials the app is redirected to https://service.app.com/index.html
In this Index.html we are making an ajax call to https://api.app.com (GET Request) to convert a cookie to token. Since this ajax request first preflight request is sent to api.app.com which is getting aborted by IE, so further call for actual GET request. We are not able to resolve this issue. Only way we can resolve this error is for the Local Intranet zone adding the service.app.com to Sites tab and enabling the access across domains in the security zone. I am not sure if this is the only solution available or anything that I can do without touching the browser settings.
