I would like to know is that possible to modify or remove Access-Control-Allow-Origin from Response Headers

Due to security reason, I need to change Access-Control-Allow-Origin from * to domain

I add in a new

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

But the header still displaying * in some of the pages, refer to the image below. enter image description here

Some other pages are reflecting the changes which is what I am looking for. enter image description here

May I know how to rectify this issue in order to make all of the page consistent?

  • @Kane the configuration you're describing is not a part of, and does not appear to pertain to WordPress. It sounds like a Microsoft IIS configuration to me, which is in general considered off-topic for our community. Your question would probably be a better fit over at serverfault – bosco Jul 19 '16 at 8:42
  • @bosco, my WordPress is running on IIS 7.0. It is not a server fault. My website still can function properly without any issue. I just want to modify the response headers only. – WeeHong Jul 19 '16 at 8:58
  • @Kane "Serverfault.com" is the Stack Exchange site that's focused on server configuration and operation - they know a lot more about IIS/Apache/Nginx than our community. Your question makes more sense there; here it may be considered "off-topic" since you're not actually asking anything about WordPress =] – bosco Jul 19 '16 at 9:00
