httpd(8) - Cross-Origin Resource Sharing (CORS) header

Hello All,

Is there a way to add a CORS header to httpd(8) responses for static
content?

Here is a summary of the issue:
    Client request -> httpd Server1
        Server1 response ->  Client
            Client jS xmlhttprequest for static content -> httpd Server2
                Server2 response -> Client
                CORS block, due to missing CORS header in Server2 response

I have not found a way to add the CORS header value for static content
from httpd(8).  Am I missing something here?

To work around this, I have created CGI to add the header and return the
file contents.  The CGI script does not add much value.

I believe relayd(8) could add the header.  This solution would add a
layer of complexity that I prefer to avoid.

Both of these solutions add complexity that would be avoided entirely if
httpd(8) could be configured to add the CORS header.

I see three options:
    1. Create a diff that adds a server CORS property to httpd.conf(5).
    2. Create a diff that adds generic header NVPs to httpd.conf(5).
    3. Create a local patch to hard code the header, along with existing
headers.

If there is not an existing solution, is there any interest in adding
the CORS header as a feature of httpd(8)?

Thanks,
