How to add cookie when proxy_pass via programming?

Hey, I want to add custom cookie when proxy pass to the upstream in my
custom module. I want to implement like what this config does:

proxy_pass http://servers;
proxy_add_header Cookie “$http_cookie;KEY=VALUE”;

But sinc the VALUE is dynamically generated so I need to add this cookie
via programming.

How to do that?

Thanks very much.

Create a module that defines a veriable and use it in
proxy_set_header Cookie “$http_cookie; key=$var”;

Thanks. And I want to know the time when “proxy_set_header” is executed,
because the my cookie value is related to the chosen upstream server. So
will proxy_set_header happen before upstream peer initialization or
after that?

Before, and this value is used for all upstreams.
