See more:

For a project deployed in the server, it is needed to make all of domains that contains "myCompany.com" accessible. It works if using

HTML

<add name="Access-Control-Allow-Origin" value="*" />

But not if using

HTML

<add name="Access-Control-Allow-Origin" value="myCompany.com" />

How can this problem be handled? Thanks.

I don't think this is supported out of the box, you'd need to explicitly add all of your sub-domains to the allow list. I'm sure if you google "iis access control allow origin sub domain" you'll find various solutions, pick one that suits you.

Solution 1

Enable CORS for specific domains in IIS using URL Rewrite[^]

Looks like there's ways of defining a range of URLs

I have found the solution for this problem. The approach is described below:
1) In the IIS7 Manager, click the project.
2) From the Feature View, click the icon for HTTP Response Headers.
3) For the "Access-Control-Allow-Origin", enter the values like that (having a single space between):
http://myCompany1.com http://myCompany2.com http://myCompany3.com
Remark: It has been done manually through IIS Manager, NOT on web.config. The revised values CANNOT be overwritten into the web.config.
