You have nginx on port 9000 which does "proxy_pass 
http://www.myserver.com:10085;;.

You want responses from the upstream port 10085 to include this extra header.

Put "add_header Access-Control-Allow-Origin *;" in the same location{}
as the proxy_pass.

You can test, using something like "curl -v", to confirm that the response
to a request to port 9000 does not refer to port 10085 at all, and that
it includes the extra header.

Thank Francis for your help.

I just install nginx_substitutions_filter from source. It works well as
expected.  I have a special requirement I will describe below.

I have a host Nginx server running in port: 9000, This Nginx will proxy
http://www.myserver.com:10085/. Some pages from
http://www.myserver.com:10085/ have a lot of iframes whose srcs are
http://www.myserver.com:10088/ and http://www.myserver.com:10089/. I cannot
get access to http://www.myserver.com:10085/, http://www.myserver.com:10088/
and http://www.myserver.com:10089/. I want the pages from
http://www.myserver.com:10085/ to have CORS( add_header
'Access-Control-Allow-Origin' '*').  How do I achieve this?


Thanks,

David

You (probably) don't.

https://www.nginx.com/resources/admin-guide/installing-nginx-open-source/

describes how to build from source in general;

https://www.nginx.com/resources/wiki/modules/substitutions/

describes how to include the modules you mention, in specific.

> Should I unstall Nginx first?

You can run "nginx -V" to see the "configure" arguments that were used
to create your current version. Then add the extra bits that you want.

Depending on precisely how you installed your current nginx, you probably
*do* want to uninstall it before installing the new one.


If your current nginx supports dynamic modules (1.12 does), and if
this extra module you want supports being built as a dynamic module,
then you may be able to build-and-add the module.

I suspect that in your case, you will probably find more clear
documentation on how to build-and-maintain a new nginx than how to
build-and-maintain the extra module.

I also suspect that, based on parallel mail threads, you probably do
not need the extra module.

It is still useful to know how to add a module that you want, so it is
certainly worth trying it on a test system, at least.

Good luck with it,
