Adobe Target Access-Control-Allow-Credentials

[asasasdas12]

Hi,

We are working on a PoC client-side integration with Adobe Target from localhost.

When we use Firefox or Safari we are facing the following warning: 

Cross-origin redirection to http://*******.tt.omtrdc.net/rest/v1/delivery?client=*****&sessionId=fba29007855b477c9a070c6e0c240f2a&version=2.10.2 denied by Cross-Origin Resource Sharing policy: Credentials flag is true, but Access-Control-Allow-Credentials is not "true".

Is it possible for Adobe Target server to respond with the Access-Control-Allow-Credentials header set to "true" to allow the cross-origin request to include credentials? or do we need to build a proxy in the middle?

In addition, we are thinking to create a CNAME to avoid CORS issues, could this CNAME solution to solve the above issue?

Thanks
